[Python-Dev] patch: try/finally in generators

[Oren Tirosh]

http://www.python.org/sf/584626

This patch removes the limitation of not allowing yield in the try part
of a try/finally. The dealloc function of a generator checks if the 
generator is still alive and resumes it one last time from the return 
instruction at the end of the code, causing any try/finally blocks to be 
triggered. Any exceptions raised are treated just like exceptions in a
__del__ finalizer (printed and ignored).
