Wouldn't it have to be 2/ here?  What in the proposal prevents code from
doing this?

  tx.waitUntil(new Promise(function(resolve) {
    setTimeout(resolve, 5000);

That seems like a good thing to me, though.  It would be nice not to
require code to perform work synchronously on the main thread in order to
have a large transaction.  This tx.waitUntil() now lets code yield the main
thread for large transactions.  If I understand it correctly...
