I'm fully aware of that. I maintain a 30,000 line Java applet for
a living (among other things).

Well, that depends on the system.

I've had no problems with the 1.1 AWT. Swing is intentionally designed
not to be threadsafe, I believe. But surely the whole point is moot with
a Java /server/.

Well, I didn't say it'd be 'nicely'. Java isn't my ideal server
implementation language either. But merely having lots of threads isn't
likely to be the biggest problem.
