no for protocol level

I can understand a yes to this one for sql level, because it will be
hard to clean up by hand :-( But I like the analogy to hold cursors, 
so I would also say no to sql level.

Is the pro yes argument ACID allowed here ? I thought ACID is about 
data integrity and not flow control, and also deals with main transactions 
and not subtransactions.

NO for both SQL and protocol level.
The analogy is imho that closing a 'hold cursor' is also never rolled back

Sounds like a good plan, but also sounds like a lot of work.
