There's nothing specific to this case built in, and you're right, there are
many possible solutions. The easiest may be to submit your requests via a
common function that increments a counter with each request. Your event
handler(s) can then decrement the count upon receipt of the response, and
perform the final action when the count goes to zero.
Does that do what you're looking for?
