If the socket is in non-blocking mode and connect blocks, then you get
a Unix.EWOULDBLOCK error. According to the MSDN documentation, if
connect fails with EWOULDBLOCK, you have to wait for the socket to
become writeable then call connect again which will fail with EISCONN
if the connection succeeded.
