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