Er, I believe that Win95/NT Java does this right now. PLEASE don't anyone
write code assuming that certain threads don't preempt each other. Your
code will fail on Java's biggest platform in subtle, bizarre and
non-deterministic hard-to-track-down ways - Heisenbugs.

Good move. The less stuff exposed the better, especially writeable public
instance variables.
