-- if another user deletes a transaction, or an account, there is no way
for us to know. Thus, any sort of sync will probably (incorrectly)
add the deleted transaction back in. Question: what is the best way

currently have an opinion on the 'best' way of dealing with this
situation. A reasonable solution may well be 'don't do that'.
-- Implement PR_BALANCE query type in gncquery.c. This query is
supposed to return unbalanced transactions from the database.
I think it might be better to leave this unbalanced, and just
plain force everything in the database to be balanced. In this
case, we should then modify the code to check for unbalanced
transactions before commiting them, or otherwise force the backend
to run in balanced mode. We could set 'force_double_entry=2'
but this is currently unimplmented in the engine. Alternately,
we could call 'Scrub' at appropriate times.
