I find mozilla being unstable if you compile in unmodified.

I posted about the DNS settings 28/01/04, for some reason our getaddrinfo() do 
not appear to be thread safe, or at least it can (easily) stall forever. I found 
if I take out "_PR_HAVE_GETADDRINFO" in ./nsprpub/pr/include/md/_netbsd.h it
run _a lot_ better. Even with NetBSD 2.0 RC4.

Another issue is it frequently runs out of shmem. Not sure if it is leaking, or 
just never releasing it. This is noticable when you view photoshop competitions 
and so on. Increasing shmem in your kernel config (or gdb your kernel) improves 
this. "ipcs -m" shows you used memory IIRC. This becomes a bigger burden if you 
use X11vnc/x0rfbserver as well.

Apart from those two, 1.7.3 has been very stable.
