And [ruby-core:8555] and the thread started from it?

Indeed.  It should contain the word "real" as well as the
document of proc_getgid().

Since Process.gid= is inteded to set real gid only, keeping egid,
use of setgid() is not appropriate.

As for Mac OS X, setrgid() fails like as setregid(), since the
former just calls the latter.

Well, it feels reasonable to me.

That assumption is false.
