DynamicScraper closeFactory() seems to have memory leak

[ahashp]

I'm running nodeJS v0.10.35 on Ubuntu 14.04.1 LTS.
I read your documentation and calls

• scraperjs.DynamicScraper.startFactory()

before I request multiple pages in parallel to scrape.
On completion of all the scraping, (using Promise). I would call

• scraperjs.DynamicScraper.closeFactory()

However, looking at the memory usage, after a few hundred rounds of function calls. I see there are a bunch of processes belonging to phantomjs sitting there using up memory, eventually the system runs out of memory (4G) and nodeJS crashes.

I looked through the source code for this PhantomPoll class, I don't see any where it close the "Page", is this close() for each page needed to release the memory? could this be the reason for the memory "leak" that I see? Could you please spend a little bit of your time to help check? much appreciated.

I think the leak is not directly from the scraper/node process, but rather a mismanagement of the phantom pages. I had some issues with it in the past.
I'll take a look into it in the next couple of days. Thanks for your input.
