Yes, let's take a break from this.

I will need some help identifying the main developer APIs that need to
be handled in this way. Although, I am hoping that as I dive in, it
will become obvious.

I might wait to do this until I am tacking the issue of removing the
various threading shells.

OK, that makes sense, I will try to keep the discussions here.
