Replying to [comment:44 mcs]:
> I did not look at the backported patches; do I need to? They are large;
I guess if they merged cleanly they are probably okay.
I think those are OK -- they're just pulling in the update patches from
jemalloc.
> Enabling the redzones and abort options might make TB slower and less
stable. But I guess finding lurking bugs is a good thing as long as
performance is not reduced too much.
Both these comments are true. Seems like the alphas is the right place
until we observe performance and how crashy the browser is. One thing I
can try in the near future is to push this patch to Mozilla's try server
and look at crashes and talos (performance) results.
