Thats extra complication that wouldn't be necessary if updates specified the 
node.  Line based updates also mean taking the table offline (totally 
unacceptable) to do a complete copy/rename, using transactions (may not be 
available), or a post-diff comparison of the old and new tables to determine 
whats changed and update the live table accordingly (*shudder*).
