This might be the best solution ... as it minimizes the 'smoke and mirrors'
factor that solution #2 presents ... (if people need to sync with the
database, let them do it explicitly ... don't do it implictly ... )

This should be a fine solution too ... I tried this just to make sure that
it didn't already work ... sadly, it doesn't cause any data to get written
out ... Ideally, it should do a read from the DB too ... just to make sure
that no data has been modified by other processes (yes, i use commit B)
since the start of the transaction ...

I think that for BMP, that will actually work ... since you're calling a
method with implementation from within the same object, it should work just
fine.
Ok, so now the million dollar question ... :) ... is there any chance that
this can get stuck into 2.3/2.4? or is this a big deal that can't be
implemented in time? ... We are coming up against a launch date for our
project and this is really important ...
Should I add this to the "bug database" (even though it's not a bug, per
say) ?...
