Thanks Mike! So, seems like it increases both disk and cpu use after some time. If the user just read the article and go out I don't think that they saw it occurring.

And thank you for the article. Simple, well written and right on point. Keep it going ;)

Yeah I had a similar problem, my cursor was also jacked on the page. had delayed scrolling and could not click on links. Had to refresh the page.

Got the same 6GB of RAM 99% CPU, didn't debug why yet.

Pegged CPU with FF 51 also.
