OFS.CopySupport._getCopy() and ZODB.ImportExport._importFile() (called from _getCopy()) uses
transaction.savepoint(). If the current transaction uses a DataManager which doesn't support savepoint, the copy operation will fail. Since the savepoint feature is used to replace the old commit(1) call and is not meant to be rollback, it would be better to use an optimistic savepoint which won't make the operation fails if a DataManager doesn't support optimistic savepoint.
