+Summary: Poll Times out on Sockets which have been closed
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+If you perform a socket.Poll(timeout,SelectMode.SelectRead) on a socket
+which has been closed by the remote server the poll will wait for the full
+duration of the timeout before returning false. When this is attempted with
+the .Net implementation the Poll returns immediately if the remote socket
+is already closed. Note: the socket.Connected property will be unaffected
+by a Poll.
+
+Steps to reproduce the problem:
+1. Create a socket object and Connect it to a server, sleep for a while
+2. The remote server should close the socket 
+3. despite the remote end being closed the Socket.Connected property will
+still return true (this what .Net does)
+4. Perform Socket.Poll() with a non zero timeout
+(5. after the poll returns false the Socket.Connected property will still
+return true)
+
+Actual Results:
+On mono the Poll will wait for the full timeout to elapse before returning
+false
+
+Expected Results:
+On .Net the Poll will return false immediately.
+
+How often does this happen? 
+Always
+
+Additional Information:
+I only tested this with SelectMode.SelectRead - the .Net behaviour should
+be replicated for all SelectModes.
