Test case

If there are no references to a dedicated worker object and no messages are sent to its worker context(which would increment unconfirmed messages counter which in turn would protect worker from being collected) then it may be garbage collected before a first message from worker context arrives. See attached page where messages from the worker context never reaches worker object. This works fine on other ports that use in-process workers.
