1866465 - Handle special message types

Status: RESOLVED FIXED

(Core :: Fuzzing, enhancement)

Description

[Christian Holler (:decoder)]

There are a number of message types that are handled internally in the IPC layer and will never end up as MessageTasks. There is two problems with this:

1. They need special synchronization, otherwise they will cause timeouts (as they will never generate a MessageTask even though the implementation expects one).

2. Some of these messages can cause ports to go away, etc. causing the follow-up messages to be useless, so we should release after sending such a message.
