Why the extra shells?

I have tried to leave a shell suspended every which I way I can think  
of, but can't make it happen, so the problem doesn't seem to be  
caused by not typing 'exit' to leave the shell...

I killed off all those shells and don't see any ill effects, so  
apparently they weren't started by some running process that depended  
on them.

I'm sure I did something wrong to create these zombie processes...  
will keep digging to see what it might have been...
