Can hitting resource limits be more friendly?

I often see new Squid users bumping against process size resource
limits (such as on FreeBSD), and being displeased that Squid handles
them so gracelessly (i.e., coring).

Is there anything that can be done to make this more friendly -- e.g.,
dynamically reducing cache_mem, or even just exiting more cleanly,
with a clear error message?

Cheers,
