Prefer xrange over range for small performance gain.
range() allocates an actual list when called. xrange() is just an iterator
and creates the next range item on demand. This provides a slight
performance increase.
In python 3, range will do what xrange does currently, but the upgrade will
be handled by the 2to3 tool.
