Yes, it is on my todo list. I've already gotten rid of localtime/gmtime
and used localtime_r/gmtime_r, and I'm going through the entire list of
functions noted not to be thread safe from "man pthreads".

However, it seems the biggest issue now are some of our own functions
that are not re-entrant that Hugh pointed out.

But I'll rewrite all the crypt() functions to use crypt_r() as well.
