Thanks Olivier.  At least I'm not imagining things.

Does this hint at scalability problems if I'm suffering this 
problem with zero load yet didn't suffer from this on a CGI-based
web server with very heavy load ?  Or is this (as I hope) just an 
initial cost of running PCGI/Zope that won't be extrapolated 
with load ?

I've had a couple of "Python exit on signal 11" problems too - again on 
a development machine (ie. next to zero load) but assumed that's because
I was doing something spazzy with a 500,000-record DB.

Ah, ok - maybe I'll try that though I'm almost certain that that will
cause more of the first problems (above).

I don't think so. It's a very well endowed machine <g> and was working 
completely fine on a diet of pure 100% CGI.
