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.
