Well, I recompiled Python 2.1.1 with py_malloc turned off. Then I 
recompiled Zope and ZPatterns. (I don't know whether I really needed to 
recompile Zope and ZPatterns.)

Result: no signal 11 crashes in 36 hours. I was getting one at least 
every couple of hours before, often more frequently, depending on the 
system load. Zope is now back to it usual stable self.

Thanks for the information, Andy. Also thanks to everyone else who 
offered advice on this.
