There doesn't seem to be any option to gulp-ruby-sass that would help, and there's been an open GitHub issue about this problem for a couple of months now, so I think you'll have to make due with a hacky workaround.

The only thing I can think of is to split up all your SCSS files into batches and invoke sass once for each batch then merge the resulting streams using merge-stream.

In order to do this you have to first find all your SCSS files, which means you need to use glob directly.

Here's what such a solution could look like:

var glob = require('glob'); 
var merge  = require('merge-stream');

var maxArgs = 1000;

gulp.task('compile-css', function() {
  var files = glob.sync(src + '/app/**/*.scss');
  var stream = merge();
  while (files.length) {
    stream.add(sass(files.splice(0, maxArgs), { base:'app' }));
  return stream
    .pipe(gulp.dest(dest + '/app'))
    .pipe(browserSync.reload({ stream: true }))

You'll have to play around with maxArgs to find a value that works for you.
