// 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.
