The previous commit (8bb93c6f) using async_safe_run_on_cpu() doesn't work on graphics sub-system which restrict which threads can do GUI updates. Rather the special casing MacOS we just directly call the helper and move all the exclusive handling into do_dafe_dpy_refresh(). The unfortunate bouncing of the BQL is to ensure there is no deadlock as vCPUs waiting on the BQL are kicked into their quiescent state.
