[Leaplist] For that rare occasion of an errant app causing Linux system freeze

[patrick]

Any OS can suffer from an errant application causing it to seemingly
freeze up, and here is how to safely exit that problem...
 I believe I have seen this happen to a system about a dozen times since
1997.  Oh, yeah, I know how to delete the 'right' character in
/etc/fstab, to cause calamity!

No code is perfect, so this can come in handy!
