High CPU usage #6

The plugin mostly works on my MacBook (OS X 10.11), but an Atom Helper process sucks a lot of system time. I tied it to ide-haskell-hasktags by disabling it.

Sorry for not providing more information for reproduction, I'll maybe add something later.

I'm terribly sorry about late response, I read this on a train and then promptly forgot about it completely until today.

ide-haskell-hasktags automatically re-runs hasktags if any haskell files are changed in project directory. To facilitate that, it relies on chokidar. On OSX this boils down to subscribing to FSEvents. While initial directory traversal can take up a considerable amount of resources, it usually dials down a lot after that. On larger directories, I think it might take a while though (e.g. if you open a Haskell file from home directory)

If it doesn't sound like I'm describing your particular case, then I have no idea what goes wrong for you, or even if it's a problem related to your particular configuration (since I don't have a spare Mac to test on...)

TL; DR: Check if this problem persists on really small projects (like one Haskell file in a directory or something like that).

Sorry for procrastination.

I tried it on a stack new tmp project and have not encountered the issue so far, so not sure about reproducibility. I'll tell you if I hit this again.
