Hi Imran, 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 --Guido On Wed, Mar 19, 2014 at 11:07 AM, Imran Geriskovan < imran.geriskovan@gmail.com> wrote:

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
