Currently, fs.existsSync is implemented in terms of fs.statSync. I think this module can copy that logic and be much simpler as a result.

statSync already follows symlinks automatically and throws an ENOENT error on broken symlinks, unlike lstatSync, so no special handling is needed for that.

This is the cause of broccolijs/broccoli-funnel#81, more details there. I'll try to add a failing test and maybe even a fix.

I think we should phase out this package, we can simply rely on fs.existsSync

We should prevent getting stuck following symlinks that refer to each other.

/a.js -> /b.js
/b.js -> a.js

We should throw an error if a circular symlink is detected.

For reasons beyond the scope of this ticket my project uses dir names that include .. and therefore path like /home/code/test/compare/master...jcsrb are possible and the way this module detects if the path is relative https://github.com/ember-cli/exists-sync/blob/master/index.js#L18 gives a false positive and causes broccoli-funnel which uses this module to fail

Preparing PR with failing test , will add ASAP
