I guess that the reason you're trying to improve the performance of this
loop is that you have already decided that it's not performing
adequately.  In other words, this isn't premature optimization...

If that's the case, have you considered trying either going down into C
or using Pyrex to see if the performance increases?  You might just be
able to do a "strcmp()" in C fairly easily, or you may be able to push
more of the code in this loop into C.  You should definitely look at
Pyrex if you have performance critical code, though.

 of the week debugging Monday's code.  -- Christopher Thompson
