which makes it impossible for teardown to delete the file on Windows,
which causes this test to fail, and also "the next" test to fail because
its setup can't delete Source.fs either.  So explictly close the storage
iterator.

After the merge, I made several Python 2.1 compatibility changes for
the auth code.

transactions on both sides of it.  The coarse granularity of time.time()
on Windows causes this test to fail sporadically otherwise.

MappingStorage (it doesn't support undo).

Remove comments out test.

Disable test for ZEO + MappingStorage, since it doesn't support undo.

storing a 128K transaction note and it shouldn't cause this test to
fail.

Disabling the test by commenting it out.

New tests covering corner cases in the storage API, derived from code coverage analysis of DirectoryStorage. FileStorage currently fails checkCreationUndoneGetSerial

Check whether a registered extension method already exists before creating the marshaller attribute. This allows for a smooth migration should a former extension method be promoted to the normal storage interface.

Remove signals file, since the only signal you actually need to use is
for log-file rotation.

A few changes to the rST formatting.

Update the ZEO tests to use the new configuration language.
Remove files from old configuration approach.
