No, but select() probably wouldn't return EBADF if a bad descriptor
were specified in the bitmap.
Did using kqueue w/rtorrent work in an earlier kernel? It still feels
like it's a different problem but the only way to really tell would be
to instrument the kernel with some kprintf()'s for kevent() to track

fail with that error (instead of recording it in a returned event
list). Presumably some descriptor within that event list has been
