> Using the linearstore overwrite-before-return option can cause excessive 
> client latencies owing to the time taken in the store to overwrite the entire 
> journal file with zeros in an inefficient manner.  The store by design does 
> not have its own worker threads, and relies on the thread that is processing 
> a message to perform its work.
