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 :-)
