Only if those fds are below ~1024 or whatever. (If you're going to use one of the legacy interfaces, at least poll() doesn't have arbitrary limits on the numeric value of the fd.)
1024 is the default fd limit anyway, isn't it?
...because of select, and how it became essentially impossible to ensure that a process wasn't using it anywhere, indirectly or incidentally.
