Do I need to worry about disposing chokidar watchers?

This isn't a bug report, so I'm not sure if this is the correct place to put this. Please redirect me if necessary.

I'm working on adding file-watching support to a Rollup plugin (rollup-plugin-copy) using Chokidar (see this discussion for why we want to use Chokidar: vladshcherbin/rollup-plugin-copy#27 (comment)), and I'm wondering if I need to make sure I call FSWatcher.close() before the process exits. If so, I'm not sure what the recommended way to do so is, because using process.on('exit', ...) requires the callback to be synchronous (see https://nodejs.org/api/process.html#process_event_exit), but FSWatcher.close() is async.

Since I'm here, I'm also curious regarding the best practices for creating more than one FSWatcher instance VS creating a single master FSWatcher with all of the paths you care about. Is there a significant performance cost for creating multiple watchers?

You don’t need to call close() before process exit.

Creating more than one instance is possible, but may create some bugs, since we don’t test this case.
