ACK, of course, but this brings up something else:  what's the status of 
moving chip reset outside of a spinlock?

Currently a reset during operation can trigger the CPU lockup detector 
and other doo-dads, because you can easily spend a second or two with a 
spinlock held (a loooooong time, to hold a spinlock)
