FF 3.6.12 also doesn't spin the CPU, although it's substantially slower than Chrome.

Just to be clear, I'm observing this on Linux x64.
A TM tip build doesn't have this problem. Neither does m-c if I disable tracejit. Sounds like a dup of that bug njn wants sayrer to merge to m-c... ;)
(In reply to comment #5) > A TM tip build doesn't have this problem. Neither does m-c if I disable > tracejit. Sounds like a dup of that bug njn wants sayrer to merge to m-c... ;) Which is the one from bug 609129, which needs the patch from bug 607856 as a precursor.
Verified fixed in the latest nightly. Marking as a dupe of bug 609129.
