Looking good at my end. The only packaged version of this I could find
btw was the daily pyRXP CVS snapshot (in case you were hoping for a 
wider
distribution).

setup.py duplicates the rxp source files for the 16 bit build. You
might want to remove them in a try: finally clause, as if I do a
'sudo python setup.py install', they end up being owned by root. Or only
copy the files if the dest file doesn't exist or is out of date.

There is still a double free around, and I can trigger it with my
test suite. It seems to be in the parser cleanup routines. I'll have
a closer look at this when I get a chance, but anyone more familiar
with malloc debugging and the time is welcome to do it for me :-)
I've attached the test cases that can trigger the issue in case anyone
is feeling enthusiastic. This particular problem should only bite people
who are parsing XML from untrusted sources since it takes particularly
broken XML to trigger the malloc errors as far as I can tell.
