> SingleSender blocking rpc thread

>
> When the send fails in SingleSender, the listener calls stop(), which creates
> two problems. First, stop() calls the cleanup() method, which can cause
> buffers to be removed while the execution thread is still using them. Second,
> this method blocks on waitForSendComlete(), and we never want to block the
> rpc thread, as this can lead to the drillbit becoming unresponsive.
> The stop() method should not be called by thread other than the execution
> thread.
