This feature was previously available only through the SIGUSR2 signal, which meant it wasn't available on platforms that don't have UNIX signals, such as Windows and with applications that already use SIGUSR1 for something else. Now we have action-signals for doing the same. These action signals can also be used for fetching the checkpoint information programmatically instead of printing to the debug log.
