I wrote a script recently which is able to track a segfault down to the
last successful Python call.  I used sys.settrace().  I've been
considering adding such a thing as a z2.py command-line option with two
levels:

--trace-calls: log all method calls to a file.
--trace-everything: log every Python instruction.

To narrow down a segfault, you would first invoke with --trace-calls,
and if that doesn't give you enough info, you would invoke with
--trace-everything.

To eliminate huge log files, the "Houston, I just forked off a kid"
daemon could set up a socket to which the main Zope process sends the
information.  When the segfault occurs, the main process would copy the
last 50 calls to the log file.
