Unfortunately, for some of us Netscape dying is not the problem. Netscape
*hanging* is the problem. For me, it appears to be related to DNS lookups
*and FreeBSD 3.0.

If I run with MOZILLA_NO_ASYNC_DNS (ie. no DNS helper process), I often
get hangs. This did not happen with FreeBSD 2.2.8. It appears to happen if
name lookups take "too long". If I prime the cache on the DNS server (eg.
by looking up the name manually beforehand), *or* if I let Netscape start
a DNS helper process, I don't get these hangs.
