Can we fix the ticket notification mailings some day? It's been almost four
months now.

Re: the patch. I noticed the replacement of the signed type int by an
unsigned size_t. This is a risky sort of thing and needs to be checked. Nor
is it clear we should use size_t instead of one of the python or numpy
types. The use of inline and the local declaration of variables would also
have been caught early in a code review. So I think in this case the patch
should have been discussed and reviewed on the list. An internal discussion
at Enthought doesn't serve the same purposel.
