I've just discovered `tryto`. Sadly, but looks like there some race
condition bug in it when tryto used to run some process which exit
very quickly. I've tried to run `tryto chpst -l`, noticed strange
results and moved to more simple examples like `tryto true` (see
details below).

Of course, I mean -l option here, not -L.
Another fun thing is timelimit(8) mentioned on tryto(1). Google doesn't
know what is 'timelimit(8)' or know but refrain from saying to me. :-)
powerman@home ~/tmp $ for i in $(seq 1 10); do echo "i=$i"; tryto -v -t 2 bash -c 'true'; done
i=1
