Description
During checkpointing, the slave pauses the task, updates its task data on the server and resumes the same task immediately. However, the slave should pause the task, send it back to the server and receive another task (may be the same if no others are available).

Currently, the following default settings are used:
- CheckpointInterval (time of continuous calculation after which a task is sent back): 18 Hours
- CheckpointCheckInterval (time between checks whether or not a task should be sent back): 5 Minutes
If required, I can adjust these as well.
