> Here is how current updateReaders is implemented in StoreScanner:
> {code}
>   // Implementation of ChangedReadersObserver
>   public void updateReaders() throws IOException {
>     if (this.closing.get()) {
>       return;
>     }
>     this.lock.writeLock().lock();
>     try {
>       // Could do this pretty nicely with KeyValueHeap, but the existing
>       // implementation of this method only updated if no existing storefiles?
>       // Lets discuss.
>       return;
>     } finally {
>       this.lock.writeLock().unlock();
>     }
