Google released several things as open source today:
http://code.google.com/

Their CoreDumper library is actually very cool, and I hacked it into an
apache module:
http://www.outoforder.cc/projects/apache/mod_coredumper/

Just do a 'SetHandler download-core', and you can download a GDB
computable core file, from the instance that the request took place.

I am not sure how useful it will be in the long run for debugging, but I
think it could be nice for taking snapshots mid-processing in the
multi-threaded MPMs.
