Hmmmm....  I'd call this a "locking" problem rather than a
"synchronization" problem.  And you're right: there are few good
cross-platform mechanisms for this.  Here's a question: does your
service permit you to run a stand-alone process?  If so, make that a
socket-based database server.  This would also make your code run
generally faster.
