Fixed a bug in the Socket that would throw an exception if there was just too

much data in thou outgoing buffer on a write and you need to wait.  Instead
the write operation returns zero right now if that happens.  It should be the
only case that it returns zero in when there are bytes to be written and an
exception is not triggered.
