The python-dev list is not the place to ask questions about the usage of Python modules or features. However, since you are asking an asyncio-related question, you should be welcome at the python-tulip list: https://groups.google.com/forum/?fromgroups#!forum/python-tulip

Code below has been written with the intension of acquiring ONLY one lock.
There are two issues:

1- Sometimes it returns more than one lock in done.
2- Sometimes, even if wait exits with zero or one locks, it seems
there are other locks are acquired too. Though, I couldn't isolate
the exact case for this.

It sounds like some background shield() is at works.

I kindly request your comments.


locks = \[some asyncio.Locks...\]
sel = \[Pack(l.acquire(), l) for l in locks\]
done, pend = asyncio.wait(sel, timeout=10, return\_when=FIRST\_COMPLETED)
...
@coroutine
def Pack(co, obj):
� � yield from co
� � return obj
