First class heap allocations from different threads

[robertblaketaylor]

I was interested in using the direct heap functions for tracking heaps directly in our codebase, but see the caveat that:

but can only allocate from the same thread that created it.

Do you have any plans on removing this restriction?

Yes, I am planning to add this but it is not entirely trivial to do in a performant way. Currently working on improving behavior with many threads being created/terminated and blocked threads but I hopefully get to fc heaps after that.
