As the branch description says:

"Hacks to get python backtraces out of core files using some code i 
found under a rock to talk to gdb's "machine interface"."

It's a bit rough around the edges but it's probably useful.  I should 
polish a bit and announce it somewhere I guess...

To use it, run "python backtrace.py $pid" or "python backtrace.py -c $core".

Cheers,
mwh
