Interesting idea. Maybe I'll leave it on for a few minutes, idle, and see if 
it keeps making noises after it has been spinning for a while.

As an aside, it turns out that on CDMA at least, the list of cell phone 
numbers that should start ringing during this 1.25 time fits in one or two 
packets, and is sorted by phone number, so while you're listening, if you 
hear a higher phone number in the list, you can power down. It turns out you 
have to adjust the sleep timer depending on how many phone numbers you 
listened to, because running the receiver heats up the quartz crystal 
differently depending on how long it runs, so the timer runs at a different 
speed, and you'll miss your wake-up window if you don't.  Pretty intensely 
complicated inside there.
