------- Additional Comments from Dmitry Titov <dimich at chromium.org>
Now that the preparatory patches are in, this change is simple:
- Change MessageQueue to act as a queue of OwnPtr<DataType>
- Remove ThreadSafeShared from various Task types.
- Replace a bunch of RefPtrs with OwnPtrs when dealing with those Tasks
