I'm aware of the thread stack issue because it bit me when I first
installed Zope on FreeBSD (i386).  But the Ports Makefile now contains

.if !defined(WANT_HUGE_STACK_SIZE)
CFLAGS+=                -DTHREAD_STACK_SIZE=0x20000
.else
CFLAGS+=                -DTHREAD_STACK_SIZE=0x100000
.endif # !defined(WANT_HUGE_STACK_SIZE)

which fixes the problem--at least on i386.  I've tried building Python
with these and larger values (up to 0x500000), but the behavior didn't
change.

Furthermore, even with a small stack Zope started on the i386; now
on the Sun it crashes almost immediately:
