Which is exactly what we did on our project .. each Lua VM was event driven from an event queue and each event call was monitored for time via debug hooks and memory usage via a custom allocator. We then built a dispatcher using an OS thread pool to drive the VMs. The fact that we could do all that without a single patch to the Lua source was a testament to its clean design.

And imho that is the point of Lua .. it’s a clean efficient building block you can mold to your needs, not an imposing edifice that must be used in a particular manner.
