Yeah, but the timing for "reliably" doing that appears to depend a lot on what else is going on -- could be 1 second or 5 or 15 -- and it's inefficient to sit there and wait or poll if you don't have to. That's why I'm looking for a reliable "yes, you can proceed, it's ready to go" indicator. Leaving the default as the current somewhat async behavior is OK, but I'd really like a "block until you're absolutely sure the action is complete and functioning" option.
