Condition.wait_for_any() would create a single inner lock and add it to the
_waiters list for each of the condition variables. notify() and notify_all()
would need to deal with the possibility that releasing the inner lock fails
with ThreadError because it has already been unlocked.

(Ignoring timeouts) wait() should be used with the idiom
while <expr>:
cond.wait()
This allows the woken thread to check whether it is really supposed to continue
--
it sounds like you are not doing this. The only advantage of using wait() over
wait_for() is that sometimes it avoids you having to create a named function or
lambda function like in
cond.wait_for(lambda: not (<expr>))
