My PC has 2 cores and Maxima never uses more than %50 of the available CPU time.  I have written screen savers that use %100 percent but who cares about that.  I don't use them.  Why fry my CPU?

SBCL supports threads.  I think openmcl does too.  Maxima doesn't use 
any threads so I don't know what benefit you might see, if any.
