> Currently injected pauses make threads sleep for a specified time. This can
> be an enhanced to stop the thread indefinitely using a CountDownLatch. It is
> quite similar to how cancellation works.
> Tasks:
> (a) Add another message to RPC layer to signal paused remote threads to
> resume (through ControlHandler) by counting down. Complications if the thread
> has not reached the pause site yet.
> (b) Add resume signal (like ctrl-c) to sqlline
> (further enhancement: another signal to trigger pause from sqlline)
