I am unsure because that can result in out-of-memory, and so make a particular deoptimization event impossible to process - while it is an unlikely corner case, the constraint does not currently exist as far as I know.

That's a good point, and it's worth thinking carefully about.

My concern, in case it is not clear, is that the complexity of this PR (49 files) is not justified by the magnitude of the problem.
