Example uses:

The use case with --module 8192 was causing some errors from
stress-ng having unexpected bail out messages before ramp up.

I forgot to remove this stray comment.
No worries, I can fix that up when I apply the patch.

So here was the reason for the complaints, Although changing this to
return just EXIT_NO_RESOURCE cures the warning, I don't think the
non instance 0 workers are doing anything then. Is that right Colin?
I'll have a look at that when I test this out later tonight.
