Thanks again, Bernie for your help.  It's a good doc, but I could not
find any reference to interrupt sharing and at most only a brief mention
of isrs at all.

I now believe that shared interrupts can happen concurrently, both MPU
and DSP requesting service at once with one interrupt.  This may explain
where interrupts are being lost.  The sbhwpg is not clear on this point,
and I had assumed it did not happen.  Catching this state to see for
myself was tricky but I think I saw it happen.  Time to rewrite the
isrs..
