Newer versions of `tap` run more asynchronously, so sometimes using `process.nextTick(process.exit)` to end a test would prevent the test from completing correctly. Removing all instances of `process.nextTick(process.exit)` put tests into three categories: * the test still worked correctly -- no fixup needed. * the test would hang because the VM's `_steppingInterval` was keeping Node alive. These tests call a new `quit()` method which ends the stepping interval. * the `load-extensions` test needed special attention because the "Video Sensing" extension starts its own loop using `setTimeout`. I added a `_stopLoop()` method on the extension and directly call that from the test. I'm not completely happy with this solution but anything more general would likely require a change to the extension spec, so I'm leaving that as a followup task.
