If the cacher hasn't seen any event (when lastProcessedResourceVersion is zero) and
the bookmarkTimer has ticked then we shouldn't popExpiredWatchers. This is
because the watchers wont' be re-added and will miss future bookmark events when
the cacher finally receives an event via the c.incoming chan.
* 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
testing.T.Cleanup ensures the environment is restored after a test and
any of its parallel sub-tests. It's possible that these can be
simplified further to T.Setenv(key, ""), but I did not investigate.
T.Setenv ensures that the environment is returned to its prior state
when the test ends. It also panics when called from a parallel test to
prevent racy test interdependencies.
