Thanks for the tip, and it looks like the right thing, but adding
entries for core and rebooting does not help. I then tried upping a
brute-force limit of zero imposed in the daemon startup function in
/etc/rc.d/init.d/functions thinking that inetd or loginout or somesuch
process might need to be higher (since all children inherit these
limits apparently), but that does not seem to help.

It is set to zero in /etc/profile, and commented out in
/etc/csh.cshrc, but afaik anything set at that point should be able to
be set higher later. There is a cryptic comment in /etc/profile saying
that "for bash2 it can't be set higher for user processes", but I
don't know what that's about.

Can someone running a Mandrake6.1 or RH6.1 system take a look at their
system limits (for csh use "limit", for bash use "ulimit -a"). Are
they greater than zero for the coredumpsize??
