Description Dmitry Sivachenko 2009-06-18 13:50:00 UTC 
Sometimes when OS is running out of swap, swap pager can kill important
processes like inetd, sshd, etc.

This patch adds '-i' (means "immortal") option to inetd, which,
when specified, will set P_PROTECTED flag for inetd process, preventing
swap pager to kill inetd.

This will allow at least to login to the affected machine (via telnet or
ssh if sshd is started from inetd) and fix the issue.

This patch was made against inetd found in 7.2-STABLE.

attilio added this functionality to inetd (and other important 
daemons) in rev 199804.
