So did I.  That is, until I stumbled across that behaviour ... Never
found any mention of it in the ATmega168's data sheet (that's where I
encountered it).


I too would not have suspected it as debugWIRE is performed on the RESET pin.

Did a project with a '168 debugged and programed via debugWIRE which most all tasks the AVR performed were communicating to hardware via SPI.
