Are you sure you are approaching the problem from the best angle? Akka gives you a guarantee that the execution of actor code is single threaded, so each time a message is processed, the code has an "exclusive lock" on the actor's internal state (quotation marks because there is actually no lock involved, just smart thread scheduling).
Does your writer need to exchange several messages with the target actor, and the messages from readers should not be processed over the duration of that conversation? In such case, you should be able to implement it with little effort using become [1] and Stash [2]. For extra style points, you can use FSM [3] :) Just watch out for unbounded mailboxes when using Stash! Stashing large number of messages may exhaust heap space.
