The standard says negative fd's are ignored. We get that right. What we
are left with is an overly paranoid check against max_fds. This check
should go away. You should be able to pass in up to your rlimit fds, and
let negative ones (holes or tails) be ignored.

I am saying there is no problem.

In both cases, for a properly written application we ignore the
invalid fds. The behavior is identical both before and after
your change, so there is no reason to make it.
