USE... EXCLUSIVE opens the file exclusively - no other user can open the table, not even for read/only.
flock() locks an entire file. If you do this, a second user can not use flock() or rlock(), but can still open the table for R/O access.
rlock() locks a single record. No other user can lock this record, until you unlock it.

Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
