GOAL:
Is the shared memory block locked for the time of a read even with NO-LOCK on the record?
FIX:
Yes, a TOREAD (shared) lock.
The shared buffer lock is held as long as it takes to read the record data out of the block. If the record is fragmented then there is a "record getlock" lock which is maintained across all the block accesses needed to copy (put together)the pieces of the record into the users record buffer.
