-//  HttpServerPropertiesManager
-
-// The manager for creating and updating an HttpServerProperties (for example it
-// tracks if a server supports SPDY or not).
-//
-// This class interacts with both the UI thread, where notifications of pref
-// changes are received from, and the IO thread, which owns it (in the
-// ProfileIOData) and it persists the changes from network stack that if a
-// server supports SPDY or not.
-//
-// It must be constructed on the UI thread, to set up |ui_method_factory_| and
-// the prefs listeners.
-//
-// ShutdownOnUIThread must be called from UI before destruction, to release
-// the prefs listeners on the UI thread. This is done from ProfileIOData.
-//
-// Update tasks from the UI thread can post safely to the IO thread, since the
-// destruction order of Profile and ProfileIOData guarantees that if this
-// exists in UI, then a potential destruction on IO will come after any task
-// posted to IO from that method on UI. This is used to go through IO before
-// the actual update starts, and grab a WeakPtr.
