Well, it supports numeric log levels, and you can define your own log 
levels too.

I'd suggest the transaction code either logs at a numeric level:

logger.log(-100,...)

or we define another logging level for TRACE:

import logging
logging.TRACE = logging.DEBUG - 10
logging.addLevelName(logging.TRACE,'TRACE')

...which can then be used in the transaction code as follows:

logger.log(logging.TRACE,...)

cheers,

Chris
