Comment(by sjamaan):

 There doesn't seem to be a way to count them except loop from zero to
 FD_SETSIZE and doing an FD_ISSET check.

 You can't even compare with FD_ZERO because the implementation is (allowed
 to be) an array of elements, which means you'd just be comparing pointers.

 We could keep a shadow copy around in Scheme as a list and use that to
 count the set size... Checking for the empty list is simple enough.
 Keeping it synced shouldn't be hard, but of course it's a little annoying.
