I also propose to half badness of processes with pid < 1000 - those processes are usually also important, because they are called during boot-time and they usually handle important system affairs.

The belief that boot started processes remain under a pid < 1000 is flawed. Simple example: the postfix mail server.

agreed, but FWIW my postfix master daemon is pid 434

Ah, yes that reminds me that when you take down a service and then start it again, you lose that nice low pid. FWIW, my master is 23034 now. As D Ford stated, paying attention to pid value is not useful.

On a server which is anything but idle, 16bit pids cycle every 1 or 2 days. And many daemons do get restarted (syslog on RH systems), and they do fork to perform their task (all from [x]inetd, sendmail, and the like). PID means nothing, expecially when uptime > 100 days its pretty much a random number (a lot of chances you already restarted almost everything, unless your configuration is *very* stable).
