Comment (by cypher):

 Twisted has a `which()` in `twisted.python.procutils` that could be used
 in place of `shutilwhich` (though it returns a list of filepaths):

 https://twistedmatrix.com/documents/current/api/twisted.python.procutils.html

 For simplicity's sake, it might be better to just use that instead.
