Combination of lint + test coverage report throws

[nkbt]

I see it pretty awkward. Same issue for concurrently

21:03 $ `npm bin`/parallelshell '`npm bin`/eslint .' '`npm bin`/karma start ./karma.conf.js --single-run --reporters coverage' -w

fs.js:691
  return binding.lstat(pathModule._makeLong(path));

@nkbt can you try using the parallelshell in #30 and see if that works any better for you?

Checked out #30

parallelshell@2.0.0 node_modules/parallelshell

Run. All good, but...

I doublechecked by running it again and it failed! Then again and it was ok. Then one more - failed: https://gist.github.com/nkbt/768cde05020c004659e4

Removed node-modules, made clean install. All is the same. Task every other time.

When I add -w it seems to fail more consistently (like, every time) but exists with success code 0

I think your setup might be a red herring because parallelshell should not be affecting files and folders, the error you get is coming from eslint, not parallelshell:

fs.js:691
  return binding.lstat(pathModule._makeLong(path));
                 ^

Without -w the ouput is exactly what I'd expect - for whatever reason eslint is failing, and you get a non-zero exit code whenever that happens, and everything closes down. Certainly -w should still exit with non-zero; not sure why that's not happening though.
