The idea with this commit is to implement a timeout functionality that does not rely on a system utility (such as unix `timeout`). Tests could hang because of a CPU-bound task and, as a result, we need to handle timeouts in a separate process. An ideal implementation would first spawn the timeout, which in turn would spawn the tests, acting as a supervisor and making sure they do not exceed the supplied time. However, setting up such an environment would have been trickier, thus the test process spawns the timeout cop before running any test. This, in turn, invokes a `setTimeout` function and kills the parent process as soon as the timeout gets triggered, logging to console the reason why the parent process was killed (and exiting the parent process with code 130). I haven't used `Task` because, in order to log stuff to the console, we need to fork the ChildProcess from `remote`, as otherwise nothing gets written out.
Atom is a hackable text editor for the 21st century, built on Electron, and based on everything we love about our favorite editors. We designed it to be deeply customizable, but still approachable using the default configuration.
