I'm pretty sure Emerald has a memory leak or other shutdown/cleanup
problem. My workstations can run for WEEKS without crashing if I don't run
Emerald, but when I do, more than a few times, a crash can't be far behind.
That's not empirical evidence that it *is* Emerald, mind you, but it's
pretty good circumstantial evidence.
