** Faster DOM <==> JIT Interaction
** Shumway and IonMonkey JIT code-gen caching, Till Schneidereit
*** Memory Lazy function cloning- if compiled in one apartment clone to others instead of re-compiling*** Disk Caching- investigate disk caching for functions*** Re-Lazificiation of functions - memory savings for cold byte code (JITs already do this for codegen)
* Hygiene
** Remove Jaegermonkey JaegerMonkey code from the tree
