e.g. further improve subprocess interrupt, exceptions, and termination.
2. Remove the workarounds in PyShell.py and ScriptBinding.py involving
interrupting the subprocess prior to killing it, not necessary anymore.
3. Fix a bug introduced at PyShell Rev 1.66: was getting extra shell menu
every time the shell window was recreated.

threading modules. Can debug user code which imports these modules,
though.
2. Re-enable debugger in PyShell.
3. Remove old code implementing previous approaches to this issue.

is now interruptable on Windows.
2. Tweak signal.signal() wait parameters as called by various methods
to improve I/O response, especially on Windows.
3. Debugger is disabled at this check-in pending further development.

1. Clarify that rpc.SocketIO._getresponse() currently blocks on socket.
2. Improve exception handling in subprocess when GUI terminates abruptly.
M run.py
Move exception formatting out of rpc.py. This allows each end of the
link to format and print exceptions how and where it sees fit and makes it
easier for threads to display their own exceptions.

Clean up the way IDLEfork handles termination of the subprocess, restore
ability to interrupt user code in Windows (so long as it's doing terminal
I/O).
1. Handle subprocess interrupts in Windows with an RPC message.
2. Run/F5 will restart the subprocess even if user code is running.
3. Restart the subprocess if the link is dropped.
4. Exit IDLE cleanly even during I/O.
4. In rpc.py, remove explicit calls to statelock, let the condition
variable handle acquire() and release().

SF Bug 676398 Doesn't handle non-built-in exceptions
1. Move exception formatting to the subprocess; allows subclassing of
exceptions, including subclasses created in the shell without
introducing excessive complexity in the RPC mechanism.
2. Provide access to linecache from subprocess to support this.
M RemoteDebugger.py
M rpc.py
Fix the incorrect shell exception tracebacks generated when running
under debugger control:
1. Use rpc.SocketIO.asynccall() instead of remotecall() to handle the
IdbProxy.run() command.
2. Add a 'shell' attribute to RemoteDebugger.IdbProxy to allow setting
of ModifiedInterpreter's active_seq attribute from RemoteDebugger code.
3. Cleanup PyShell.ModifiedInterpreter.runcode() and remove ambiguity
regarding use of begin/endexecuting().
4. In runcode() and cleanup_traceback() use 'console' instead of 'file' to
denote the entity to which the exception traceback is printed.
5. Enhance cleanup_traceback() so if the traceback is pruned entirely away
(the error is in IDLE internals) it will be displayed in its entirety
instead.
6. ModifiedInterpreter.runcode() now prints ERROR RPC returns to both
console and __stderr__.
7. Make a small tweak to the rpc.py debug messages.
1. Format and print exceptions raised in user code.
M rpc.py
1. Additional debug messages in rpc.py
2. Move debug message enable switch from SocketIO to Client and Server
to allow separate activation.
3. Add indication of origin (client or server) to debug message
4. Add sequence number to appropriate debug messages
5. Pass string exception arg as a string rather than a tuple.
refactor a bit and clean up.
M PyShell.py Cosmetic changes, delete blank lines, add # on some
blank lines.
M rpc.py Add more debugging capability
M run.py Add support for getting calltip from subprocess
Move import statements
instead.
2. Preserve the Idle client's listening socket for reuse with the
fresh subprocess.
3. Remove some unused rpc code, comment out additional unused code.

the Idle debugger.
M PyShell.py : Call RemoteDebugger.close_remote_debugger()
M RemoteDebugger.py: Add close_remote_debugger(); further polish code used
to start the debugger sections.
M rpc.py : Add comments on Idlefork methods register(), unregister()
comment out unused methods
M run.py : Add stop_the_debugger(); polish code
Use a repr() on the subprocess side when fetching dict values for stack.
The various dict entities are not needed by the debugger GUI, only
their representation.
