Right. The optimization in this case is that the runtime could delay
loading B and, if B is encountered, *block* the currently running
event loop and fetch B.
So the spec is that import could nest an event loop? What scripts or
event handlers/timeouts/etc. could run at that point? In general
breaking the run-to-completion execution model means the importing
script and its containing window could be destroyed, a zombie.
