Yeah and we're making some pretty heavy use of it within Firefox OS.

We've got bug 1027381 [1] though we might want to introduce a mechanism
to also throttle the requests we send (and drawing the spinner which
takes a huge amount of CPU time slowing down the user).

Having previously worked on a couple of GCs I must say this is amazing

This morning I've been asked to do a review for bug 980027 [1] mostly
because I've been working actively on that code and I did some small
reviews in the past. Since the change was relatively large this time
