Well, I did say "I'm not sure what the best approach is to fix it" !

Michael's version of this is much more complete, but requires oodles
of changes to the various headers which try to put a value to
FD_SETSIZE. This is still only a partial answer, since the value of
FD_SETSIZE doesn't change when you change the hard upper limit on the
number of file descriptors.
