Summary: yield allowed in try/finally

Initial Comment:
A generator's dealloc function now resumes a generator
one last time by jumping directly to the return statement at 
the end of the code.  As a result, the finally section of any 
try/finally blocks is executed.  Any exceptions raised are 
treated just like exceptions in a __del__ finalizer.

The GC will need to be taught about these finalizers.  Look
for the
method 'has_finalizer' in gcmodule.c.  I don't think we want
that
method to return true for all generator objects since that would
cause any reference cycle containing a generator to become
uncollectable.
