Well, ssockets is very low level.

fpselect() is mostly useful when you combine multiple file descriptors at once. 
Although it can be done, IMHO it makes little sense to create a select() method 
on the socket stream, since it would only have one socket handle.

You can perfectly do a fpselect() with the handles of the streams that ssockets uses.
