* This has been necessary due to the undefined call order of of static objects. Fixes #12315. * The bug has been caused by the linker which free unused resources, making the BMediaRoster to run in a zombie state. In this state anything such as a message could make the looper to crash. * The class is reintroduced with some differences though, we are going to protect it from another thread calling Roster() while the BMediaRoster is quitting and implement BMediaRosterEx::Quit. * Unregister registrar notifications before we quit our thread. Avoid to uninitialize anything from QuitRequested as it may cause problems.
