Make your Electron apps load faster, with this One Weird Trick
// Include this at the very top of both your main and window processes, so that
// it loads as soon as possible.
//
// Why does this work? The node.js module system calls fs.realpathSync a _lot_
// to load stuff, which in turn, has to call fs.lstatSync a _lot_. While you
// generally can't cache stat() results because they change behind your back
// (i.e. another program opens a file, then you stat it, the stats change),
// caching it for a very short period of time is :ok: :gem:. These effects are
// especially apparent on Windows, where stat() is far more expensive - stat()
// calls often take more time in the perf graph than actually evaluating the
