 Unfortunately the test system won't crash even though I've been running
 "build.sh" and building packages with pkg_chk on it all afternoon.
 
 I'm guessing this means the problem is somehow more closely related to
 the networking code.
 
 (though the test system is mounting /usr/src, and /usr/pkgsrc, and
 distfiles, all over NFS)
 
 The production server where the problem was observed runs a rather
 heavily used Cyrus IMAPd, among other network services such as HTTP,
 FTP, DNS, SMTP, etc.  The crash happened in imapd both times, almost
 immediately after the system gets to multi-user mode (I was able to
 login via SSH once, but only just barely before it crashed).
 
 I'll try installing Cyrus on the test box tomorrow and running as many
 simultaneous connections against it as I can.  Maybe the POP benchmark
 from benchmarks/postal will help.
