And don't foolishly think that there is only one set of _r variants
out there. There are several different signatures for getpwnam_r,
for example.

From Todo:
the _r-problem: for all the {set,get,end}*() system database
calls (and a couple more: readdir, *rand*, crypt, *time,
tmpnam) there are in many systems the _r versions
to be used in re-entrant (=multithreaded) code
Icky things: the _r API is not standardized and
the _r-forms require per-thread data to store their state
