There are some cases, can't recall exactly what they are, where a single ref is returned instead of a ref, class info tuple.

must've used this to disable the exception handling temporarily to debug the exception formatting machinery, and forgotten to re-enable it before checking in. Unfortunately, this made it into the ZODB 3.1 release, making this a 3.1.1 backport candidate.

Added a new test: checkMultiStorageTransaction(). This tests for the deadlocks that we've seen when multiple appservers do transactions involving multiple ZEO 2.0 storages. It also nicely tests the timeout feature that Jeremy added to StorageServer. WARNING: with the current ZEO code, this occasionally hangs. That's the point of this test. :-)

If a transaction takes a long time to complete after it has the storage lock, close the connection and abort the transaction. The abort may cause the client to be hosed. XXX There should be a configuration option to enable / disable this feature. That should be done before too long. When a transaction takes a long time to complete, it is often a sign of deadlock involving multiple storages. Until the possibility of deadlock is eliminated, this feature will prevent an entire ZEO cluster from deadlocking (on writes).

As the comment said: Not really necessary in production code... disable this before release, providing noone has been reporting and RuntimeErrors that it uses to report problems.

XXX This creates a new requirement: If a store implements restore(), it's iterator() implementation must support the data_txn option.

The Record() object now has a data_txn attribute that is either None or the id of the transaction that contains the data used by the current record. Example: When transactionalUndo() modifies an object, it typical creates a new data record that points at the transaction before the undo. The new record contains the same logical data as the record it refers to. (For consistency purposes, this is a stronger claim than that the pickles in two different data records are the same.) Add a test of the new iterator() feature in TransactionalUndoStorage.

Share backpointer implementation between _loadBack() and _loadBackPOS() to avoid duplicate code. Simplify interface between FileIterator and RecordIterator. Don't pass unused arguments and don't pass nested tuples. Use global variables to hold trans and data struct formats. Reformat several docstrings. Add whitespace to RecordIterator so that I can read it.

This change is an untested improvement. If some object is in the index but unloadable for some reason, report it along with the traceback. When possible, report what objects refer to the un-loadable one.
