I have same problem on mozilla-gtk2-1.6nb1. When I opened a lot of tabs
all at once, it has happened. It hungs at getaddrinfo(3).
IMHO, in mozilla/nsprpub/pr/src/misc/prnetdb.c, DNS lock/unlock is necessary
for getaddrinfo(3). Please try a following patch. On my system mozilla seems
to be fine with this patch.
