The idea was to indicate if the process is likely to be causing a locking
problem - but now I think about it, a more useful pice of information would
be if any tables/rows/whatever are locked in such a way that another user
might be prevented from doing an update. Is this possible?
I would maintain that if possible, it is useful to distinguish logical
'read-only' transactions from TXs that might lock another user.
