[JDEV] jabber users limit !!

[David Waite]

Note that recompiling the kernel is only neccessary with 2.2 and 2.4 if you are
trying to scale with select(). Using poll() (i.e. jpolld) does not require this
change, just setting of the ulimit and tweaking the header file for jpolld to
set the maximum connections.
