Details

As soon as we JIT compile a script, we create a JitRuntime and generate some shared JIT stubs. With some work we should be able to share (most of) them, or make them per-process.

This should save some memory per runtime (~50K on x86 IIRC). (A bit hard to say though because JIT code is stored in 64K pools.)
