A few comments:
2) one of the benefits of wait_for() is that it automates the tricky timekeeping needed if one wants an somewhat accurate timeout, you may want to mention this specifically.
3) the offending part. I see that you don't want to use the technical terms of spurious wakeups or stolen wakeups. That's ok, but the resulting explanation is somwhat bogus. I suggest the following:
The ``while`` loop checking for the application's condition is necessary
because :meth:`~Condition.wait` can return after an arbitrary long time, and the condition which prompted the :meth:`~Condition.notify` call may not yet, or no longer, hold true. This is an inherent property of multi-threaded programming and the use of this pattern is essential for the robust use of Condition objects.
