Description Simon Fraser (smfr) 2012-05-25 11:42:06 PDT
We don't think we're getting any benefit from RenderLayer being arena-allocated, and it adds code complexity.

How is RenderLayer different than the other Render* classes WRT usefulness of being arena-allocated?
Comment 3 Simon Fraser (smfr) 2012-05-25 12:47:00 PDT
There don't tend to be that many RenderLayers on most pages (tens - hundreds, not thousands).
Comment 4 Ojan Vafai 2012-05-25 13:03:17 PDT
Fair enough.

Comment 9 Alexey Proskuryakov 2013-10-11 09:53:46 PDT
This caused crashes on tests (debug and release WK2). Very strange that EWS didn't catch it, was the landed patch identical to the one posted here?
