Does the RLIMIT_NPROC trick work against oping, or any setuid app
that calls setuid(getuid())?

This should work for everything that calls setuid()

I have a little bit about this here:

My previous web search did find that one.  Though set_user() doing
NPROC check is only called when new uid differs from current real uid
(so not called in setuid(getuid()) case).
