Some quick results of timing:

(-T3) -- I tried reducing the timing to the default, with no change in behavior:

$ /usr/bin/sudo /usr/bin/nmap -sS -T3 -p 1-65535 74.62.92.70 -P0 -v

(-T2) -- I tried reducing the timing further to -T2, and that seemed
to help a lot!  Unfortunately, it also estimated about 8 hours to
complete.  Not so helpful, as doing "--scan-delay 1ms" results in an
accurate scan in ~7 minutes.

But "--scan-delay 1ms" only worked 40% of the time...so perhaps I
should try some different (larger?) scan-delay values on some of the
hosts where 1ms still resulted in a crash.  I'll go off and try
that...
