Certainly. posixmodule.c is traditionally the place for wrappers around function supported one atleast some Unixish systems; it contains already functions less useful than sendfile.

I did some quick hack to use 'setproctitle' of sendmail. I think it is very useful for daemons to show their status. I'm sorry but, can you review this for posixmodule candidate, too?

I tested only on FreeBSD and Linux.

DEMO on FreeBSD

Thank you!
