[Python-Dev] Non-blocking (asynchronous) timer without thread?

[Evgeniy Khramtsov]

The question to python core developers:
Is there any plans to implement non-blocking timer like a 
threading.Timer() but without thread?
Some interpreted languages (like Tcl or Erlang) have such functionality, 
so I think it would be a great
feature in Python :)

The main goal is to prevent threads overhead and problems with race 
conditions and deadlocks.

Thanks in advance!
