tbh I am super bothered I cannot figure out a test case to at least occasionally fail. I explain the basic issue in #4304 (more specifically #4304 (comment)). Summarized as two threads both decide to build something and one is a child closure and the other is a parent of that closure. We get a sequence like:
This code will ask hard scope to full build itself for blocks and the two entry points to building on IRScope will built the closures before the parent. It does not appear to infinite loop so yay? I could not see anything bust with this change and I think the intent is clear but I am unsure in best particular impl to use. Part of it is based on children wanting parent info for passes vs parents wanting children info for passes.
@subbuss I think you have best knowledge of these expectations and @headius I would like your thoughts as well.
