Nah, my contact list counter (for sending the list) was overrunning the end
of the list.  So icqlib was storing loads of useless entries in its own
list and that was using up tonnes of swap space.  Heh heh.  FIXEd.

Yeah.  So far it's working nicely.  Have a temporary ICQ account created
for testing and debugging (don't know how to create accounts with icqlib
yet); logging in and out work, the userlist looks good.

Yeah, but that was a moot detail for the purposes at the time.  I've got
a usleep() working, but I'd rather use SIGALRM tuned to microseconds, and
delay for 50,000 of those.  (50ms).

Checking out the icqlib source, I noted that all callbacks are nullified,
so anything I don't use won't crash my program.  <Phew.>

Your memory leak thing is always good to check out.  No one's written up
a decent icqlib tutorial, so I'm taking that task on.  Once the basics
are known, the whole development process is pretty simple.  Save the user
interface, of course.  Heh.  Still racking my brain about the best way to
do that under console.

(I'm thinking something like zicq would be nice, but have the userlist on
the left hand side of the screen and have scrolling and filtering caps.)
