It is not doing that. Currently it has LWW semantics for “basic”
kv, and set semantics for “list” kv.

Emacs lock file is slow so kv-* is not doing locking and leave the
responsibility to caller. persistent-value-* does locking.

Writes from other instances is not immediately visible, but I could
make that happen. Not sure if it’s useful though, unless someone
want to (ab)use it as an IPC channel.
