What is bad is an *unintended* loop that goobles cpu time while outputting 
nothing.  Example:

def fact(n):
  res = 1
  while n != 0:
    res *= n
    n -= 1
  return res

fact(-1)

Now imagine that you are paying $360/hr ($.10/sec) (for IBM mainframe time) 
and you should understand the bad reputation (and why jobs were submitted 
with a time limit!). ;-)
