Indeed it does - although implemented in a somewhat convoluted way:
A lock *is* a context (or is that "context manager"), i.e. it implements
def __context__(self): return self
__enter__=acquire
def __exit__(self,*args): return self.release() #roughly
A _Condition *has* a lock, so it could become the context (manager?)
through
def __context__(self): return self.lock
However, instead of doing that, it does
def __context__(self): return self
# roughly: __enter__ is actually set in __init__ to self.lock.acquire
def __enter__(self):
return self.acquire()
def __exit__(self):
return self.release
Looks somewhat redundant to me, but correct.

Martin
