[Stackless] Santa concurrency problem

[Carlos Eduardo de Paula]

Hi Chris,

take a look at the changes I made in QueuedTimer, It now uses a
heapq.. I kept the old way commented just for clarification.. Do you
think it performs better now or its the same.

For the CPU time issue, I didnt see any problems with CPU usage on
this class in my examples.. maybe someone has an issue on it...
