gdb - customize it the way <b>you</b> want

You can ask gdb to save a "checkpoint":
```
checkpoint
```
After stepping forward and finding you've gone further then you wanted, switch back to the checkpoint:
```
restart <checkpoint id>
```
To see the list of active check-points:
```
info checkpoints
```
What a checkpoint does: forks off a copy of the program, so gdb will be able to switch back to it later on.
To delete checkpoints:
```
delete checkpoint <checkpoint id>
```
