This is true of all dictionaries in Python, but this one tends to
catch people off guard as they don't realize when sys.modules might
change out from underneath them as a hidden side effect of their
code. Copying it first avoids the RuntimeError. An example when
this happens in single threaded code are codecs being loaded which
are an implicit time of use import that most need not think about.
It took me longer than I expected to figure out why a random class
I dealt with didn't support weak references. I believe this addition
will make the __slots__/weakref interaction more discoverable to people
having troubles with this. (Before this patch __slots__ was not
mentioned in weakref documentation even once).

On Unix, if the sem_clockwait() function is available in the C
library (glibc 2.30 and newer), the threading.Lock.acquire() method
now uses the monotonic clock (time.CLOCK_MONOTONIC) for the timeout,
rather than using the system clock (time.CLOCK_REALTIME), to not be
affected by system clock changes.
configure now checks if the sem_clockwait() function is available.
Having `operator.call(obj, arg)` mean `type(obj).__call__(obj, arg)` is
consistent with the other dunder operators. The semantics with `*args,
**kwargs` then follow naturally from the single-arg semantics.
The URL listed in the `logging` docs for the original `logging` module leads to a 404. I managed to find the new location for the page and updated the URL.

On Windows, time.sleep() now uses a waitable timer which has a
resolution of 100 ns (10^-7 sec). Previously, it had a solution of 1
ms (10^-3 sec).
* On Windows, time.sleep() now calls PyErr_CheckSignals() before
resetting the SIGINT event.
* Add _PyTime_As100Nanoseconds() function.
* Complete and update time.sleep() documentation.
