OSX Dynamic Scraper Error: spawn EMFILE

[vdraceil]

This happens to me more frequently (in OSX) when using DynamicScraper.
Is this possibly because of routing too many URLs? ... may be, too many Phantom instances are getting created.

child_process.js:958
    throw errnoException(process._errno, 'spawn');
          ^

Yes, it looks like the problem may be related with it.
