Yes, that's right... it didn't click when you said before you were in stand-alone mode, but that is true that checkpoints only work in full-system mode because of the way the memory module works. This is yet another thing we plan to have taken care of in v2.0, but in the meantime if you need the capability soon, your best bet is to put together serialize/unserialize support for the "main memory" object that's used by stand-alone (syscall emulation) mode.
