[PATCH] Protect inetd and cron from being killedunder high-pressure swapping

> we are considering whether a jail should have its own init...

Just FYI:

The AIX version of jails each had their own init process.  I wasnt directly working on that project/team, so I dont know all the details.  The only thing I remember was a few bugs my co-workers mentioned: first there were several places that assumed init was pid 1, and they all needed changing.  Second was I think some weird issues managing when the jails init was supposed to actually quit.  Last, when AIX wanted to send a signal to a processs parent like SIGCHILD, AIX needed to be careful which init to send it to for unparented processes, otherwise an init would get a signal for a process id it couldnt actually see.
