It tells HAL to rescan the battery - in case someone changed the battery
we want the new serial number etc... if I recall Peter's reasoning
correctly. I think this check is better done in HAL than in pm-utils; it
doesn't make sense to make pm-utils call into HAL at all - Peter, is
this fine with you? 

If so, I'll make this change in HAL for 0.5.9 (and I'll make the async
too!).
