OK, this just gets weirder.  There are different results depending on
whether you hit ^Z during the first "sleep 10", during the second
"sleep 11", or during "sleep 21".  There are also different results if
you change it to

{ sleep 5; sleep 6; } | { sleep 20; sleep 21; }

and hit ^Z during "sleep 20".  So some of what I said in workers/50901
doesn't always apply, though the location of the busy-loop is always
the same.
