And are often considered very unportable due to byte-padding.

Use the same scheme as file descriptor arrays for select.


A nice little bit array holding (oh most of the SysV systems I've been
programming on) 1024 bits.

I'm pretty sure the 128 bitvector patch at the patch site has a similiar
system, though, so don't reinvent the wheel.
