NFS locking is somewhere between insanely complicated and completely

SMB locking is incompatible with everything else on the planet. Just
don't go there.

Thanks, Andrew. Given that people want to be able to access revlibs over NFS (Hi Miles!), I think it would make sense to have an invented-here locking mechanism that would definitely work on NFS, and maybe even SMB.
