Two basic attached patches that attempt do just alloc a fixed file
descriptor for this case. Not tested at all... We return the fixed file
slot in this case since we have to, to let the application know what was
picked. I kind of wish we'd done that with direct open/accept to begin
with anyway, a bit annoying that fixed vs normal open/accept behave
differently.

Anyway, something to play with, and I'm sure it can be made better.
