I think you mean that the ThreadWrapper will be destroyed automatically when the
MessageLoop is destroyed?

This should probably become EnsureForCurrentMessageLoop, since it only works on
threads with MessageLoops, and your TaskRunner changes are intended to make this
class usable on non-MessageLoop threads.

Good point. Done.
