Sorry, something went wrong.
Just before we call the `'exit'` handlers of a Worker, we drain the public port’s message queue to ensure proper ordering. Previously, we held the Worker’s `mutex_` during the exit handler call, so calling `terminate()` on the worker could lead to a deadlock if called from one of those message handlers. This fixes flakiness in the `parallel/test-worker-dns-terminate` test.

Just before we call the 'exit' handlers of a Worker, we drain
the public port’s message queue to ensure proper ordering.
Previously, we held the Worker’s mutex_ during the
exit handler call, so calling terminate() on the worker
could lead to a deadlock if called from one of those message
handlers.
This fixes flakiness in the parallel/test-worker-dns-terminate test.
