I'm Genuinely relieved that the original poster is not a trained glider
pilot,because most people once trained are so used to speed control the
situation does not occur.
Which is why we have been talking about loosing control in clouds or
failing
to allow for the reduced VNE at altitude.
Presumably if you fly high enough you can get to a coffin corner where the

stall speed is higher than the hight adjusted VNE but we should be so lucky

as to get there.
I was impressed with the pushing to recover from an inverted dive ,not
something to try without proper training.
Fun thread ,hope the snow melts soon.

I originally posted the question and actually, I am a trained and rated glider pilot and in addition to my 28,000 hours of flight time, I'm type rated in 747, 767, 737, DA20. In my glider training, I was trained to avoid VNE but am aware that there are circumstances where one can find himself (in this case it was in CONDOR flight simulaton) in rapid buildup of speed that continues on through the yellow arch and rapidly approaches VNE. I've encountered that very situation at high altitude in Jet aircraft, in heavy mountain wave conditions. In those instances, the only available action is to kill some lift by carefully extending spoilers - it works well but gliders are a different animal and and this forum is an excellent place to go when one has a question.
