Description of change
This brings the node::MakeCallback
and node::AsyncWrap::MakeCallback
implementations into alignment in that they return early if the
nextTickQueue
is empty after processing the MicrotaskQueue
.
Include test to make sure early return happens. Test has text explaining the conditions for the test to pass, since it relies on internal mechanisms that aren't guaranteed in the future.
