One of such cases is 02479_race_condition_between_insert_and_droppin_mv
[1], yes it can be fixed (by using fixed number of iterations, or with
some bash trickery), but it is better to fix them completelly,
eventually such tests will be submitted and pass review anyway.
By allocating process group for each test we can kill all the processes
in this process group, and this what this patch does.
This will also fix some test hangs (like in [1]) as well as some
possible issues in stress tests.
