Known bugs or limitations:

- the JAVA applet time between axis is off by at *least* 2 seconds. This got to
do with doing the screen calculations, updates, and then going to sleep for the
requested time;
- in the ocasions the NIC interface goes down, the sniffserver has to be called
 again (still not sure of it);
- sniffserver leaves the shared memory behind when killed with -9. This is a
UNIX limitation, so it can't be fixed; nevertheless, sniffserver reuses it when
detected, so it isn't problematic;
- sniffclient doesn't detect the dead of sniffserver;
- sniffserver doesn't detect copies of itself running. That's the main reason
why the startup script kills all the sniffserver processes.
