15// This test ensures that the 'detach' field on processes does the right thing.
16// By detaching the child process, they should be put into a separate process
17// group. We test this by spawning a detached process, then killing our own
18// group with a signal.
19//
20// Note that the first thing we do is put ourselves in our own process group so
21// we don't interfere with other running tests.
