This fixes a data race between setting `process.isRunning = false` and then calling `CFRunLoopSourceInvalidate(process.runLoopSource)`. Process.waitUntilExit() may wake up and clear .runLoopSource which results in a fairly common crash on Windows. Put this logic in a common method to reduce drift between the Darwin / Linux and Windows code paths.

Thanks to @compnerd for finding the data race.
