* cacher: remove locking from watcherBookmarkTimeBuckets
it turns out that the watcherBookmarkTimeBuckets
is called from only three places/methods: startDispatching, finishDispatching and Watch.
All these methods acquire c.Lock() before touching watcherBookmarkTimeBuckets.
Thus we could remove explicit locking in
watcherBookmarkTimeBuckets since the access is already synced.
* cacher: rename watcherBookmarkTimeBuckets methods to indicate that proper synchronisation must be used
