Netscape Crashes OS X hard


I was running Netscape 4.74 last night (and the ONLY reason I was running it is that neither OmniWeb nor Exploder currently support Java applets), and it managed to lock OS X up HARD (no mouse cursor, even). Actually, X was probably running fine, but with the screen dead in the water that didn't do me any good. Of course, I could probably have telnetted in and killed some hung processes, but I probably would have had to telnet in as root, and who'd be crazy enough to allow that? And besides, I have telnet turned off since I'm not behind a firewall and I have a static IP address...
