+ // In a nutshell, we assume this command happens *before*.
+ //
+ // Let me make this clearer:
+ //
+ // - If we have only one client, and that client issues some
+ // operation that would conflict with this operation but is
+ // still on the pending state, then we would be sure that said
+ // operation wouldn't have returned yet, so the client wouldn't
+ // issue this operation (unless the client didn't wait for the
+ // operation to finish, and that would be the client's own fault).
+ //
+ // - If we have more than one client, each client will observe
+ // whatever is the state at the moment of the commit. So, if we
+ // have two clients, one issuing an unlink and another issuing a
+ // link, and if the link happens while the unlink is still on the
+ // pending state, from the link's point-of-view this is a no-op.
+ // If different clients are issuing conflicting operations and
+ // they care about that, then the clients should make sure they
+ // enforce some kind of concurrency mechanism -- from our
+ // perspective that's what Douglas Adams would call an SEP.
+ //
+ // This should be used as a general guideline for most commands handled
+ // in this function. Adapt as you see fit, but please bear in mind that
+ // this is the expected behavior.
