Ralf: Great!

Please keep us informed.

By the way, the valgrind results that I posted were with current SVN head of
Python built with pydebug on.  valgrind is an excellent tool, and if you are
working on Linux then I recommend that you spend a couple of minutes learning
how to use it.


Basically you just prepend the command "valgrind" before your executable name
on the command-line, and then add the following options if you want:

--leak-check=full --leak-resolution=high --show-reachable=yes

P.S.  The full valgrind command-line that I used looked like this:

rm v.* ; time valgrind --suppressions=/home/zooko/glibc2.3.5-dynload.supp --suppressions=/home/zooko/python.supp --suppressions=/usr/lib/valgrind/glibc-2.3.supp --log-file=v --leak-check=full --leak-resolution=high --show-reachable=yes /usr/local/bin/python -OO ./leakcheck.py

P.P.S.  /home/zooko/glibc2.3.5-dynload.supp and /home/zooko/python.supp
available on request, but perhaps unnecessary if your Linux distribution has
already provided good .supp files.
