(Whiteboard: [js:p2][games:p?])
If you put a printf in Compiler::performCompilation, you can see a continual low-volume stream of compilation while running BananaBread, even when just sitting still. Looking at the per-frame profile, this seems to cost 0 to 2.5ms per frame. Gaming needs regular performance so we should investigate to see why we are constantly recompiling.

Is this the same as bug 727956?

It is unclear until we diagnose why :) It does fall into the general plan for making all jit compilation a priori mentioned in comment 10, though.

Luke, Alon, is this still valid?

BananaBread specifically is now asm.js-ified, so no recompilations.
