multiprocessing.cpu_count may be a better fallback.

You don't need the ^ since match means match at the start of the string.  
And \Z corresponds more accurately to fullmatch semantics than $.

(I think the principle of including such compatibility code is fine if 
people want to use the script with older Python 3.x.  I don't have 
anything older than 3.4 (the version on Ubuntu 14.04) to hand for testing 
such compatibility code myself.)
