Don't mess with gcc--2.7.0 will be out real soon now, and will build
cleanly and happily on m68k-apple-netbsd1.0A (actually, m68k-*-netbsd*).  ;-)

If you set the nice value to something other than zero or run the server
as root, this won't happen.  It's a feature of the scheduler.  Here's
the comment from the scheduler's source:
         * Check if the process exceeds its cpu resource allocation.
         * If over max, kill it.  In any case, if it has run for more
         * than 10 minutes, reduce priority to give others a chance.
This isn't a problem for 386 owners because XFree86 servers run setuid.
