Avoid sshd, cron, syslogd and inetd to be killed under high-pressure swap
environments.
Please note that this can't be done while such processes run in jails.
Note: in future it would be interesting to find a way to do that
selectively for any desired proccess (choosen by user himself), probabilly
via a ptrace interface or whatever.
