But that's a great deal more complicated! It requires merging, and while this of course is possible, you should have mentioned it because otherwise the OP might run into problems.
A lock doesn't do the job at all. ZODB supports clustering through ZEO. Multiple ZEO clients can be attached to a single or more ZODB servers. Any kind of thread based locking is local to each ZEO client.
You have to sync a sequence generator across multiple ZEO clients, hook into the two phase commit protocol or use the conflict resolution hooks. The problem is more complex than you think.
