The impression I got is that it can, but only effectively if whoever
wrote the C compiler (and probably the chess program) remembered 
to put SWAP()'s or WAIT()'s (or whatever causes a task to relinquish 
control) periodically throughout compute-bound portions of the code.
Otherwise the rest of the programs can experience significant pauses 
when a compute-bound task ends up hogging the PC and won't give other 
tasks a chance to run.  

If I've gotten the wrong impression, feel free to correct me.
