as long as your application is designed well with regard to
transaction boundaries, you'll be fine.  Inconsistencies could arise
if your app does something weird like manually commit a transaction
and start a new one before the exception is raised...

The latter. Try it and see :)

AFAICT any uncaught exception will be published as an xmlrpc fault.
But then I think you don't have control of the fault code, if you care
about that.
