it could be made simpler still.)

- explicit push and pop methods

- backward compatible with old behavior.

Moved size-limiting-cache feature to future release, since it

tests have a clean transaction state and to avoid leaving files behind.

to abort the current global transaction before and after each test and
to create a temporary test directory to run each test.

relative path, the blob machinery used relative paths, which could
lead to breakage if an application changed directories.

blobs work for large databases on systems that don't allow many
subdirectories.

rather than a file storage. This makes interactive exploration easier.
This is tested indirectly by the ConflictResolution.txt test.  I
expect more tests to take advantage of this convenience. It would be
nice to have an explicit test.

Get WeakSet from the transaction package.

and more instructive implementation.

that were removed from ZODB.tests.util.

as easily use FileStorage.

Removed commit. It should be gotten from transaction.

Removed some test set-up and tear-down facilities that can now be found
in zope.testing.setupstack.

by mapping storage.

Removed an invalid test.  Multible arguments should be passed to
tpc_begin only for recoverable storages.

Added a working newTid that replaces the non-working newTimeStamp.

Removed WeakSet, which is moved to the transaction package.

and a changes storage.
