Review comment:
@michaelandrepearce Domenico added a rule to validate if File Descriptors
are temporarily leaking. The fix was to block until the acceptor was stopped.
That broke NetworkFailureFailoverTest, as the block was infinite
Now the fix is apply a timeout on the stop, which will fix both cases.
