The script was running in production, doing actual work. Stopping it - when you don't remember a damn thing about it and how it worked - was not an option I wanted to consider at the time.
The answer to that is simpler: Try doing the Ctrl-z/fg sequence in your bash with this one:
while true ; do sleep 1 ; done
You'll see that after 'fg', the loop ends :-)
Simply put: C-z followed by fg is not bulletproof. Not to mention that I had no idea what I was running in there, and how any signal would impact it... So I wanted to find a safer way to dump what was already there, in my shell's memory.
Anyway, I hope you guys enjoyed reading this regardless :-)
