and use it to send and check for heartbeats over any transport. Caller must supply a reset proc which is called when heartbeat hasn't been received in too long. No changes required to comms protocol, but that means the heartbeat interval is fixed at compile time: can't be negotiated, and the two ends had better agree. Currently tested with linux host and PalmOS guest, where only the first heartbeat failure is recovered from. So there's some debugging to be done still.
