We have always been interested in this feature. We'll have it
eventually, but the implementations details are important: what is fine
for a research/thesis project may not be right for a production VM.
In particular I think the mono implementation must have a very low
overhead (especially in terms of memory and system resources used):
the best effects will be achieved if the optimization is turned on by

Yep, thanks to your work we know it's worthwhile to implement it.
