I'm ok with whatever you guys come up with (baring licensing requirements).
Just one comment:

Bill, you're aware that the code for the "nobody" handling is not yet in
the Cygwin git repo?  If your code requires the patch, it won't work
with current Cygwin 2.5.2, nor with any developer snapshot.

Btw., I didn't apply it yet because I was still waiting for a mailing
list reply to https://cygwin.com/ml/cygwin/2016-06/msg00460.html
On second thought, this didn't look like a question, much.  So, what do
you prefer?


Personally I like the third variation but I'm not religious about it.
