A Condition uses a 2 lock mechanism:
- outer lock: one for all the waiters to access the Condition object
- inner lock: one for each waiter to wait on.
You cannot associate several conditions to the *inner lock*, because you don't
have access to them (otherwise I wouldn't open this issue).
You said you want to have several conditions on the lock passed by the user:
lock = Lock()
cond1 = Condition(lock)
cond2 = Condition(lock)
Condition.wait_for_any({cond1: foo, cond2: bar})
but because this "lock" object is not the one the thread is waiting on, it
won't work.

You may not need to test for a predicate when using .wait() . Only when you're
using .wait_for()
This is what I'm most interested in mimicking.
