Strange thing happened a while ago, I spawned a "user agent (ua)" process
to do some work. I returned to the window with my shell, and the user
agent stayed idle. About 5 minutes later I noticed the machine running
VERY SLOW.... then I did a ps and the ua process had 30 seconds of CPU
time and it was gaining fast... I killed the process and the machine
returned back to normal speed. Why did this happen?

When it does not have control of the current window, it calls wait() waiting for a window signal. This is not a very smart thing to do when you have no child processes. Larry Weber mtunb!law
