Fix issue #1590864, multiple threads and fork() can cause deadlocks, by
acquiring the import lock around fork() calls. This prevents other threads
from having that lock while the fork happens, and is the recommended way of
dealing with such issues. There are two other locks we care about, the GIL
and the Thread Local Storage lock. The GIL is obviously held when calling
Python functions like os.fork(), and the TLS lock is explicitly reallocated
instead, while also deleting now-orphaned TLS data.
This only fixes calls to os.fork(), not extension modules or embedding
programs calling C's fork() directly. Solving that requires a new set of API
functions, and possibly a rewrite of the Python/thread_*.c mess. Add a
warning explaining the problem to the documentation in the mean time.
This also changes behaviour a little on AIX. Before, AIX (but only AIX) was
getting the import lock reallocated, seemingly to avoid this very same
problem. This is not the right approach, because the import lock is a
re-entrant one, and reallocating would do the wrong thing when forking while
holding the import lock.
Will backport to 2.6, minus the tiny AIX behaviour change.

Issue #6846: bytearray.pop was returning ints in the range [-128, 128)

Adding tests derived from the Jython project. These are primarily tests of
'single' statements with partial sentences (so they test things like "try:" in
interactive mode). Others tests hit areas that previously failed in Jython. A
couple still fail in Jython, mainly due to the difficulty of parsing partial
sentences (but should be fixed by Jython 2.6).

Curdir needs to be in the path for the test to work on all buildbots.
(I copied this from another import test, but currently this will fail if
TESTFN ends up in /tmp...see issue 2609).

Try to fix Solaris buildbot rmtree failure in test_getcwd_long_pathnames
cleanup. If this fix works, it means that Solaris is unique among
our platforms in what happens when shutil.rmtree is called on the
current working directory (ie: it doesn't work on Solaris, but
it does everywhere else).

Fix issue 5230 by having pydoc's safeimport check to see if the import
error was thrown from itself in order to decide if the module can't be
found. Thanks to Lucas Prado Melo for collaborating on the fix and tests.
