Another good point.  I recently needed that to figure out why Zope 3
request processing threads got stuck communicating with an aspell
subprocess.  (That's when I discovered that if I apt-get install
python2.4-dbg in Ubuntu, I'll get debug symbols for the system Python.)

Is there any documentation about how to extract the Python level stack
trace when you've attached to a Python program at C level with gdb?
(One of my fantasies (i.e. projects I'll never find the time to work on)
is adding Python support to sysprof, the whole-system statistical
profiler for Linux.)
