Thanks very much for the bug report, Alan. We'll definitely look into this quickly. You're right that this method is "a bit surprising, but _very convenient_". We'll either restore that behavior in DMTCP-2.x, or else provide an equivalent way to get the same functionality.
Samaneh, would you have time today to take a first look at the issue, to see what is the difference between DMTCP 1.2.8 and 2.0?.
