A bug.  Sort of.

I added a category to NSAutoreleasePool to workaround the problem.   
See the test_nsautoreleasepool.py for details.

         NSAutoreleasePool.pyobjcPushPool()
...
         NSAutoreleasePool.pyobjcPopPool()

recycle_autorelease_pool() is documented as not to be used by the 
general public.   Looking at it, I'm not sure why the global release 
pool exists at all.
