Since the last answer fizzled, I'll try: because we have too much
cycle-counting mentality in this project.
Admittedly, strncmp() has the problem that you can get bugs like:
strncmp(mime_type[0], "text/", 6)
which are hard to see. (There are disciplines which prevent such bugs,
but they're ugly as hell.) I've never found it to be a real problem,
though.

Yah :-) But I also don't find it to be a problem.
IMO, our performance will mostly be bound by the I/O that we do (thus we
want to minimize the operation count), and by the overall system impact of
the working set size (i.e. we need to reduce our mem footprint).
Cheers,
