Trying to see if we can get mixing of output. We pipe to uniq and then check that we get the same number of lines of output as input (each call to t.py produces many of the same lines so they should all get uniqed to 1.
seq 1 20 | ./gargs -p 10 "python t.py {}" | uniq | awk '{ print substr($0, 0, 10) }'
The N lines of of "1|1|1|..." or "2|2|2..." based on the sys.argv[1] where N is chosen randomly and we have random ints between each line.
