 // The cookie monster is the system for storing and retrieving cookies. It has
 // an in-memory list of all cookies, and synchronizes non-session cookies to an
 // optional permanent storage that implements the PersistentCookieStore
 // interface.
 //
 // This class IS thread-safe. Normally, it is only used on the I/O thread, but
 // is also accessed directly through Automation for UI testing.
 //
 // All cookie tasks are handled asynchronously. Tasks may be deferred if
 // all affected cookies are not yet loaded from the backing store. Otherwise,
 // the callback may be invoked immediately (prior to return of the asynchronous
 // function).
 //
 // A cookie task is either pending loading of the entire cookie store, or
 // loading of cookies for a specfic domain key(eTLD+1). In the former case, the
 // cookie task will be queued in tasks_pending_ while PersistentCookieStore
 // chain loads the cookie store on DB thread. In the latter case, the cookie
 // task will be queued in tasks_pending_for_key_ while PermanentCookieStore
 // loads cookies for the specified domain key(eTLD+1) on DB thread.
 //
 // Callbacks are guaranteed to be invoked on the calling thread.
