Log Message:
-----------
Use Transactor attribute for Function execution.
This gives clients the ability to specify what client3.Transaction to use to
execute the StoreProcedure. (aids the remote console project)
Additional improvements and changes:
In Transact(), only rollback if the connection is not closed.
In Interchange.__call__(), use the reader() and writer() locals when
synchronizing after an error.
