Hi Lenard,

Thanks for the explanation. This actually helped a lot.
Turns out parrot has a function that emulates refcounting.
Basically it's a hash with a counter... It holds a reference
to the object as long as the counter is > 0. So if eliminating
the Py_INCREF and Py_DECREF macros entirely doesn't work,
they should be able to call parrot's function.
