Try mapping the source characters in the set to a common character (the
first in the set), then splitting using that single character:

import string
def setsplit(src, sset=string.whitespace):
    return string.split(string.translate(src, string.maketrans(sset,
sset[0]*len(sset))), sset[0])

.. I realise that sset[0] characters get 'translated' to sset[0]
characters, but I suspect that the implementation of CPython
string.translate (I haven't verified it) means that it's free anyway.

Or ... use 're'.
