[Mono-dev] stressing mono and xsp

Been testing xsp with 500 simultaneous users per second and found out two 
issues in code. Also had been getting some annoying exceptions.

-Connection.cs (i sink the disposed exception, because sometimes the socket is 
closed on endrequest right away)

	while (!stop && (UnfinishedRequests || keep_alive));
	if (requests.Count == 0) {
			socket.Close ();
			server.EndConnection (this);
			server.ReleaseBuffers (receive_buffer, send_buffer);
		catch (System.ObjectDisposedException) 
			//do nothing, already disposed on endrequest

-Server.cs (on RequestCount property)
		foreach (Connection c in connections)
			requests += c.RequestCount;
		for(int i=0;i<connections.Count;i++)
			requests += ((Connection)connections[i]).RequestCount;
		return requests;

The first aproach i didnt like it very much, is a pain to sink an exception. 
We should only make the close on one place.

The second change i didnt have more the exception that the collection had 
change, but isnt thread safe also. It resolve the problem because i think it 
was on the add and not on the remove.

A curious fact was that with the second change the pages started to be 
processed 30% faster.

Are these good changes to apply or should we make the changes another way?
