Thanks Greg, but aren't I acting by the rules?
$ cat l
set +m
sleep 44&
kill $!
$ for i in `seq 33`; do bash -xm l; done
Which gives
+ kill 5256
+ set +m
+ kill 5258
+ set +m
+ kill 5260
l: line 4: 5260 Terminated sleep 44
+ set +m
+ kill 5262
+ set +m
+ kill 5264
+ set +m
I.e., one out of the 33 cases produced the Terminated message on my one
test run.
Why must
set -m; set +m
cause a race condition?
P.S.,
$ wc -l l
3
So "line 4" is wrong too.
