#7468: incorect waiting for packets on UDP connections.
----------------------------------------+-----------------------------------
Reporter: ET | Owner:

----------------------------------------+-----------------------------------
Preconditions:
Have an UDP server.
Transform the socket into a handle.
call hWaitForInput.
When it returns True.
call recv to read the datagram.
Expected result:
it will wait for a package with the hWaitForInput.
when the package arrives (withing the timeout).
it will read it in the buffer.
(this is how it works in HUGS).
Actual result:
hWaitForInput consumes the package (I think).
recv will block until the next package arrives.
