This hask is mainly for performance tests, which should be run on a physical machine that doesn't do anything else.

Commit 5c5c7d9a was a wrong fix because RLock does not raise 'thread.error' like Lock (when releasing an unacquired lock). Python >= 2.5 raises a RuntimeError and older Python raise an AssertionError.

- Change protocol to use SHA1 for all checksums: - Use SHA1 instead of CRC32 for data checksums. - Use SHA1 instead of MD5 for replication. - Change DatabaseManager API so that backends can store raw data separately from object metadata: - When processing AskStoreObject, call the backend to store the data immediately, instead of keeping it in RAM or in the temporary object table. Data is then referenced only by its checksum. Without such change, the storage could fail to store the transaction due to lack of RAM, or it could make tpc_finish step very slow. - Backends have to store data in a separate space, and remove entries as soon as they get unreferenced. So they must have an index of checksums in object metadata space. A new '_uncommitted_data' backend attribute keeps references of uncommitted data. - New methods: _pruneData, _storeData, storeData, unlockData - MySQL: change vertical partitioning of 'obj' by having data in a separate 'data' table instead of using a shortened 'obj_short' table. - BTree: data is moved from '_obj' to a new '_data' btree. - Undo is optimized so that backpointers are not required anymore to fetch data: - The checksum of an object is None only when creation is undone. - Removed DatabaseManager methods: _getObjectData, _getDataTIDFromData - DatabaseManager: move some code from _getDataTID to findUndoTID so that _getDataTID only has what's specific to backend. - Removed because already covered by ZODB tests: - neo.tests.storage.testStorageDBTests.StorageDBTests.test__getDataTID - neo.tests.storage.testStorageDBTests.StorageDBTests.test__getDataTIDFromData

With the change in TransactionManager, there's 1 comparison less.

During 'NEOCluster.stop', there's often 1 'Serialized.background()' call too many, and when it removed the last lock of the queue, another thread would hang if was sleeping between 'q.put(lock)' and 'q.get().release()'. An easy way to reproduce the bug was to add: if cls.pending is None: time.sleep(.01) just before 'q.get().release()'
