What were you trying to do in that thread? The "while true; end" part is 
a "busy loop" and is _supposed_ to suck CPU :)

$ ruby -e 'while true; end'  ;  # suck CPU
$ perl -e 'while (1) {}'     ;  # suck CPU
$ python -c 'while 1: pass'  ;  # suck CPU

If you want to give CPU time ("yield") in a thread, take a look at 
Thread.stop.
