A modest suggestion?

Don't even try doing this until AFTER you have studied how done by a 
typical example.  Say SQL allowing multiple simultaneous users to access 
(read) and change (write) to the database. << I'm somebody who in my 
working days USED DB2, wrote batch programs reading and writing to the 
database. Even wrote something to change the STRUCTURE of the database 
(add tables, modify tables, etc.).   BUT (big but) that doesn't mean I 
ever looked at how DB2 itself was coded, how IT prevented all the sorts 
of things that could go wrong with multiple simultaneous users >>

The only simpler part of this (for gnucash) is only a single resource 
being controlled, so SOME potential problems are impossible (example: 
two resources A and B; instance one has a lock on A while instance two a 
lock on B)

Been retired for a wile now, so can't remember how much "concurrent 
processing' is taught at the undergraduate level in Computer Sciences.
