I am now assuming, from looking at the code, that newlistobject and
newinstanceobject return handles that do not need to be INCREF'd until
and unless a copy is made and associated in another location.
Is there some way from within Python to examine an objects reference count?
What about for a builtin type such as a list? This info might have helped
me to track down this problem sooner.
Sorry to waste bandwith with my earlier post :(
