Description:

I execute two similar commands (which run for unknown time) on two machines. As soon as this command finish on "faster" machine, I'd like to halt it on second machine. I tried to reproduce this case with sleep for random time in cases above. When I use --nonall halting doesn't work. Adding dummy echo with arguments make --halt work, see passing case.

Hope that I help to make this awsome tool even bit better.

Thank you, BR Karel
