        It does not work with the current clear implementation. this is what is happening:
        0) assume cache is not empty
        1) state transfer and clear happens at the same time
        2) clear (PrepareCommand) arrives first than the state
        2.1) clear is replayed. the behavior is to iterate over all keys, lock, wrap, and mark them as removed.
             however, there is no key in the cache
        3) the state arrives. it acquires locks and applies the keys (note that 2.1) didn't acquire any lock)
        4) CommitCommand arrives. For all entries wrapped, it is removed. However, nothing was wrapped so nothing gets
           removed
