Was once on my together with other OS memory manager functions, 
but postponed the work indefinetly.

If someone is willing to revive that I’d gladly assist with 
review.

Lastly on Windows it would need FlushCpuCaches call before 
executing new memory.

And ofc JIT is cool, but it would be more cool to have sane 
interpreter that doesn’t leak sooner. Simply put JIT is x5 work 
due to different architectures and seeing first-hand how it goes 
I’m not sure we want that in our compiler yet.
