Paul found logic errors in my earlier code for finding processes and sending signals. Some of the logic errors are associated with how methods behave on different operating systems. Created a darwin and linux approach and a windows approach. Signed-off-by: Brent Baude <bbaude@redhat.com> [NO NEW TESTS NEEDED]
