Shalom,

xinetd is designed for a one run at time scenario. It controls behavior of many services and is quite flexible and configurable.

crond can only be run once otherwise cron jobs might lick twice.

syslod can only run once otherwise the log fils may become corrupt.
klogd, don't know.
sshd has one process that creates child processes for each ssh connection.
Sendmail works in a similar way. One process listens and each connection gets its own dedicated process.

Process ID is assigned by system when you run a process/service, PID is not fixed for every process you run. Process ID will be different every time you restart the process/service.
