Summary: Don't pass what is supposed to be FD_SETSIZE to select; only check
         the first however many. Instinct and a quick glance at the glibc
         manual tell me this doesn't matter much these days, but in the
         context of the original implementation it's still a bug. This also
         keeps this line from being affected by whatever games we play with
         FD_SETSIZE elsewhere.
