Claw.Sockets.Non_Blocking does that under Windows.  It creates a hidden
window for the connect message, then dispatches to your When_Connect
(or When_No_Connect, if it times out) procedure.
  In fact, Claw.Sockets in the demo version (www.rrsoftware.com) uses
that mechanism internally, IIRC, for blocking sockets.  They are actually
opened as non-blocking (to allow for a time out), then made blocking
once connected.
