+generate). This is always one less than a power of two, because the server
+uses this as a bitmask. A server can give out a higher numeric than this,
+however it will be "anded" with this number to find it's entry slot. The
+reason for this is so a server which is near the maximum number of clients
+can give out more numerics than it's using to prevent a new client getting a
+numeric that was used only seconds ago and maybe get messages destined to
+the old user.</LI>
