[Serusers] Child procs

The children are not all equal. Some of them serve requests coming from
UDP, some of them from TCP and some are auxiliary, like the timer
process or the fifo server.

You can see the purpose of each children using serctl ps command.

If most of the traffic being processed by your server comes over UDP
then only the UDP receivers will be running and the TCP receivers will
be idle, but you still need them to be able to receive TCP based
traffic.

Optimum number of processes depends on your hardware and the amount of
traffic being processed. For common setups 8 children should be OK.
