Task freezing on NodeJS v6.1

[valeriansaliou]

Hey,

First of all, thanks for the great work on gulp-sass-lint!

We just upgraded from Node v5 to Node v6, and noticed gulp-sass-lint doesn't work anymore. Our Gulp lint task freezes at 100% CPU. By successive removal of some sub-tasks, we managed to identify gulp-sass-lint as the freezing sub-task.

Tried on both a Debian i386 machine running Node v6.1 and a MacOS X 64 bits machine running Node v6.1.

Configuration used:

/*
  Lints SASS stylesheets
*/
gulp.task("lint_sass_stylesheets", function() {
  return gulp.src(
    "./stylesheets/**/*.sass"
  )
    .pipe(
      gulp_sass_lint()
    )
    .pipe(
      gulp_sass_lint.format()
    );
});

We tried removing the gulp_sass_lint.format() part, which didn't change anything. The problem may come from gulp_sass_lint().
