Hmm, I guess my last message wasn't too clear.  The GC code does
not use the return value.  tp_recurse takes a function pointer as
an argument.  visitproc could possibly return a non-zero status
code but all the visitprocs in the GC return success.  If, in the
future, someone else finds a use for tp_recurse they may wish to
return a status value from their visitproc.

I have been a little sloppy with the return values since the GC
didn't need them.  My fault.  For optimal flexibility if
visitproc returns a non-zero value the tp_recurse functions should
return it instead of 1.
