I would not worry about what the ECM is doing.....  What about running the
pump dry?
The ECM won't change dramatically in a couple seconds, and if you are on/off
the throttle, probably won't change at all.  

I would think that running the pump dry might shorten it's life.  The Mike
Knell book on Chevrolet TPI and TBI Engine Swapping had a neat idea to stop
engine from dying in this situation.  He made a little reservoir box to hold
fuel that fed the high pressure pump.  A low pressure pump fed the box from
the tank.  Requires two fuel pumps, but solves the problem if you can't get a
baffled fuel tank.
