Oh, absolutely. The'd be real fd's in every way. People could use them
100% equivalently (and concurrently) with the traditional ones. The whole,
and the _only_ point, would be that it breaks the legacy guarantees of a
dense fd space.

Most apps don't actually *need* that dense fd space in any case. But by
defaulting to it, we wouldn't break those (few) apps that actually depend
on it.

I agree. What would be a good interface to allocate fds in such area? We
don't want to replicate syscalls, so maybe a special new dup function?
