I'd call that a bug in their implementation, and an amusing security hole
as well. Try calling

ofd = creat("foobar", 04755);

copy some interesting program to the open fd and execute it. Hm.

I'll send a patch to Linus that sets the uid/gid in the request. I
just hope that that won't break other servers :-(
