A good idea.  I just committed a new version of SimState.java which seems to work right.  You specify an ID like this:

java sim.app.heatbugs.HeatBugs -docheckpoint 1000 -checkpointname foo

Now it'll write out

	Job 0: Checkpointing to file: 1000.0.foo.checkpoint
	Job 0: Checkpointing to file: 2000.0.foo.checkpoint
	Job 0: Checkpointing to file: 3000.0.foo.checkpoint
	Job 0: Checkpointing to file: 4000.0.foo.checkpoint
	Job 0: Checkpointing to file: 5000.0.foo.checkpoint

If you don't specify a name, it'll use the class name as usual:

	Job 0: Checkpointing to file: 1000.0.HeatBugs.checkpoint
	Job 0: Checkpointing to file: 2000.0.HeatBugs.checkpoint
	Job 0: Checkpointing to file: 3000.0.HeatBugs.checkpoint
	Job 0: Checkpointing to file: 4000.0.HeatBugs.checkpoint
	Job 0: Checkpointing to file: 5000.0.HeatBugs.checkpoint

Hope that's sufficient for you.
