Bug Description

I hit this reproducible bug while trying out chromeexperiments.com/webgl with the daily trusty iso.

1 Go to http://umazlizer.vkcdesign.com/

2 click start

3 observe nothing much happening on screen, but top showing cpu at 100% or more

4 exit firefox (or navigate to another page)

5 observe firefox process still pegging cpu in top

Other WebGL pages seem fine, tested oimo.js and jsOrrery
