abort keyword missing documentation/doesn't work

[curiosity29]

I was answered in issue #3575 to use the abort keyword to execute an action at the end of each simulation for the batch experiment, but it doesn't seem to work as expected.

model NewModel
global
{
	int a <- 1;
	init
	{
		write "init";
	}
	abort
	{
		write "abort";
	}
}

experiment ex type: batch until: cycle >1
{
	parameter "a" var: a min: 1 max: 3 step:1;
}

Result: no "abort" was printed.

It's probably because the simulation doesn't get killed. I also tried to ask the world to die and the abort does work but then the simulation just seems to run indefinitely with no cycle elapsed.
