Just to elaborate on Frank's response, there is a reason this is not directly 
supported. The problem with simply suspending a thread somewhere in the 
middle (i.e. somehow settings its timeslice to zero) is that it might just be 
in the middle of malloc() with a lock around the heap held. Any other thread 
would then block on malloc(), possibly forever. Therefore, stop the thread in 
a controlled state using a condition.
