PS- What is "Nonexistent" process
ps -elf shows prosess states under the "S" column (ex, A for active, I
for idle, etc.). 0 is "nonexistent", but I can find any definition of
what that means. Not the same a defunct or zombied i assume, because
that shows up differently, as under CMD column.

I could be wrong, but I don't believe the 'ps' command actually locks the
process table. So, it's possible that when the 'ps' command is walking
the table of active processes it encounters a process slot that was full
when the 'ps' started looking at it and emptied out due to the exit
of that process by the time the 'ps' went looking for the status of the
process...
