Comment 2 for bug 1253833

It's just a testcase. But to make things easier lets call this line as follows:

exec really_important_command_wrapper_with_locking_and_such_stuff -c 'sleep 5 &'

And the wrapper makes really important things including calling "sleep 5" in the background. Now it would be useful to make "sleep 5" to the main process for this job so that job dependencies can trigger correctly.
