Limit the concurrent connection attempts in Windows XP. Its's only a hack.

Browse source 
Problem:
RetroShare connects to all ssl's at once. In Windows XP there is a build-in connection limit of concurrent incomplete connections.

Quote:
"The TCP/IP stack in Windows XP with Service Pack 2 (SP2) installed limits the number of concurrent, incomplete outbound TCP connection attempts. When the limit is reached, subsequent connection attempts are put in a queue and resolved at a fixed rate so that there are only a limited number of connections in the incomplete state."

This results in a high usage of the nonepaged pool and when it runs over the limit it results in the following error in the system log:
German:  "TCP/IP hat das Sicherheitslimit erreicht, das für die Anzahl gleichzeitiger TCP-Verbindungsversuche festgelegt wurde."
English: "TCP/IP has reached the security limit imposed on the number of concurrent (incomplete) TCP connect attempts."

After a longer runtime of RetroShare and a very high usage of the nonepaged pool all connections of all running programs are lost and no new connections can be made. At the end it can cause a blue screen.
