New method - Store.free(int) would increase performance and lower memory consumption
------------------------------------------------------------------------------------

                 Key: COCOON-2292
                 URL: https://issues.apache.org/jira/browse/COCOON-2292
             Project: Cocoon
          Issue Type: Improvement
          Components: * Cocoon Core
            Reporter: Krzysztof Kowalczyk


Store.free() method is invoked in loop by StoreJanitor, this usually lead to slow execution
of cache freeing. For example, EHDefaultStore has a free method implemented as: 
...
final List keys = this.cache.getKeysNoDuplicateCheck();
if (!keys.isEmpty()) {
final Serializable key = (Serializable) keys.get(0);
...

Where method getKeysNoDuplicateCheck() takes quite some time (and memory) and is dependent
on the size of memory and disk stores. Because free() is run in loop this method is invoked
each time! If free(int) method would exists, then each store could implement it in an optimal
way.
