Re: Help CPU usage at 8.9% ?

[Darin Fisher <dfisher jagger me berkeley edu>]

My guess would be that the cpu usage results from the 100 millisecond 
timeout.  I bet if you increased the timeout you would notice the cpu 
usage drop.  You have to consider how much work the bar() method is 
doing... if it doing relatively a lot of work then that would explain 
the cpu usage.
