Would we want to assert here that `Target._initializationPromises` is not
empty? We always expect at least one (Breakpoints)

This assert would let us know if we change something and went too early.

Oh, you're removing promises from the list... probably to reduce memory.

Maybe we should leave them for the assert, which seems pretty valuable. Or have
an assertion:

    console.assert((Target._initializationPromises.length > 0) ||
(Target._completedInitializationPromises > 0));

And have this increment `Target._completedInitializationPromises` as well as
remove the promise.

That keeps removing the promises at the cost of a counter for a useful
assertion.
