Hi Mike,
I tried read-locking the tables as you suggested, but regrettably it
didn't help a bit. If there is nothing running but selects on that
database, mysql shouldn't lock ever, should it? or is it locking the
table if it's doing a full table scan (why?!)?

No body has answered my question so far. Does that mean there is no way
to retrieve current row numbers in a query or no way to retrieve results

I would appreciate any help.

Is the actual data stored in the database or somewhere in the file
system? If you do not have text or blob columns you may be able to use
heap/memory tables.
