Feature or enhancement

Proposal:

The JIT optimizer is now powerful enough that with it on, it pays for the JIT.

However, we seem to still be running code without optimizations. Specifically, when we hit out of space in the JIT optimizer, we just execute the unoptimized code. This is probably pretty bad for performance.

We should stop the trace at the last "safe" point, and_EXIT_TRACE there to allow the trace to grow naturally.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
