For some reason, my last try failed. The error just wasn't getting
caught. This is an attempt to make it not listen to the `'close'` event
if the `listen` function throws, which might work? I'll reboot to test
in Windows when I have time.

`import =` and `export =` are really only intended for backwards
compatibility with CommonJS. While I really don't like the new module
system TC39 has designed for us, it's what we should be using, and
consistency is important.
