I have no clue about that win32pdhutil thingy but if it returns a list 
with pids, then why do you need the except statement? And it seems to me 
that this loops as fast as the CPU is able to, so it actually steals away 
other processe's CPU time. If you insert a time.sleep(0.5) statement (or 
something similar), you can decrease the CPU usage to a minimum.

PS. Why not use a simple:

while win32pdhutil.FindPerformanceAttributesByName(procname):
    	print "still running"
