<EM>inlist, outlist</EM> and <EM>exceptlist</EM> are bitvectors
indicating file descriptors whose I/O events should be tested.
For example, if <EM>inlist</EM>=#b0110, <EM>outlist</EM>=#b100,
and <EM>exceptlist</EM>=NIL,
then whether it is possible to read on fd=1 or 2, or to write on fd=2
is tested.
<EM>Timeout</EM> specifies seconds for which <B>select</B> is allow
