The referenced commits enavled both pkill and kill to send an integer to the killed or signalled process. The test_process now will report on the integer if sent and the testsuite changes take advantage of this new feature. Another process make/destroy set had to be made as using spawn instead of exec changes both the SID and TTY for the underlying process, making other tests fail.
