> This is the basic building block for the SUSPEND/TERMINATE functionality.
> In case of a synchronous checkpoint barrier, the checkpointing thread will
> block (without holding the checkpoint lock) until the
> {{notifyCheckpointComplete}} is executed successfully. This will allow the
> checkpoint to be considered successful ONLY when also the
> {{notifyCheckpointComplete}} is successfully executed.
