there are some very good reasons to have the option to wait for all;
module unloading comes to mind for example.
I'd not like it to automatically punt all async "inatomic" work to a
separate space; that should be an option for the caller.
If the work is not going to take long, it's actually GOOD that you can
globally synchronize for it...
