Neither was initgroups, but I implemented it for safe setuid support.
Exposing sigprocmask should be very easy.  Have a look at initgroups.c;
it's a very simple example of how to wrap a module around a simple
function.

Incidentally, if something like this was implemented, maybe it'd
be useful to move initgroups in with it into a more general "unix"
module.
