[Message part 1 (text/plain, inline)]

The flow, as I understand it looks like it will be:

1 OS reports about to sleep
2 C code posts an event
3 sleep-wake-mode processes the event
3a Tell the OS to prevent sleep (has to be done in C)
3b Call hooks
3c Tell the OS it's now okay to sleep (ditto in C)

It's 3a and 3c that I was referring to.
