I did not really talk about O_NOTRANS, in fact, I would not say anything
definite about this race without reading the code path or try it with a
debugger first...

I am not sure what again looking up "" means for a Hurd server, and I don't
have time to investigate on this right now.  Maybe a bit later, if nobody
beats me to the punch.

At one time I would like to have the pathname resolution protocol documented ;)
