Hi,

  Nor asyncio.Event.wait() neither asyncio.Condition.wait() (or .wait_for()) has a timeout parameter, while threading.Event.wait() has one.

  A timeout can be specified for the whole task using asyncio.wait_for() but it's tricky.

  I guess asyncio implementation could allow a timeout parameter (but I've not looked at the code yet). Maybe is this a feature ?

Exactly, you can use wait_for() on any async operation. Why would you like to add a timeout on each async operation, while wait_for() is available?

Replace event.wait(timeout=60) with wait_for(event.wait(), 60).

Maybe we should put more examples using wait_for() on operations commonly used with a timeout?

Guido proposed to add a timeout for some operations, but with a different meaning: maximum time without getting new events, each new event resets the timeout. It was maybe on StreamReader.readline() which uses multiple async read until it gets a full line.

New changeset 21010940f8c1 by Victor Stinner in branch '3.4':
Issue #21962, asyncio doc: Suggest the usage of wait_for() to replace
https://hg.python.org/cpython/rev/21010940f8c1

Ok, I made a minimal change to the asyncio documentation to suggest the usage of wait_for(). If you would like to enhance the documentation (ex: add some examples), please write a patch.
