Nowadays, I would recommend to always use `Condition.wait_for()` rather
than `Condition.wait()`.
A Condition, unlike what the name suggests, is just a means of
synchronization. It doesn't have a boolean state per se. You have to
manage your boolean state (or any other kind of state) separately, hence
the usefulness of `wait_for()`.
As for auto-reset events, the Windows API has them, here's an
insightful writeup about them:

But, yes, perhaps auto-reset events would be a good addition
regardless. Either through a flag to Event, or as a separate class.

Antoine.
