Well, but sometimes you don't have a core file (because you didn't run ulimit
before launching Python and the crash wasn't expected; if the crash is very
erratic, by the time you've fixed the system limits, you don't manage to
reproduce it anymore, or it takes hours because it's at the end of a very long
workload). Sometimes you don't have the gdbinit file around (for example,
Mandriva doesn't ship it with any Python-related package). Sometimes you are
under Windows.

etc. :-)
