EMFILE, too many open files on Mac OS with JSON API

[jareguo]

readJson relies on jsonfile module, which just uses the original node fs module. It will cause the EMFILE error on Mac, so it's better to use graceful-fs everywhere to avoid the EMFILE problem.

@jareguo good point. Would you submit a PR in jsonfile?

[jareguo]

Sorry I don't have much time to submit a PR (and test it) lately, I just bypassed all json API in my project.

Seeing the same on Windows when writing JSON files in a loop (but waiting for the outputJson callback to fire before going through another iteration to prevent stacking up the writes). Nearly 200,000 iterations occurred before the EMFILE exception was eventually thrown.

Perhaps the callback is firing before the file is truly closed, allowing a variable number of handles to be left open when in a loop situation?

I'm getting this error when using walk too..

I'm working on fixing walk.

Done jprichardson/node-klaw#10.

When that is merged and klaw makes a new release, this can be closed.
