Energy harvesting enables intermittently powered devices to compute without built-in power. But frequent power failures, combined with nonvolatile memory intended to protect computational state, introduce strange control flow that turns sequential code into unwieldy concurrent code: programs must grapple with their own state from previous interrupted runs. This paper describes the broken time machine problem for these devices and outlines potential solutions from the perspective of safe concurrent programming.
