IAsyncResult wait() has a race.

[jgh-ds]

The wait() method of the IAsyncResult has a race. If it is called after the asynchronous operation has completed, the Condition wait() will be stuck forever.

The attached bug.py.txt file demonstrates the problem. The key to triggering it is to call time.sleep(1) before calling wait().

Basically, the handlers.utils.AsyncResults.wait() method needs to only call the condition.wait() if the result is not ready(). I've attached a git diff output to illustrate the fix.
