Overpressure 380?

Posted this somewhere else too, in case it seems "vaguely familiar"...
But - in lieu of my understanding of a blowback action (all pressure is devoted to retracting the slide and propelling the bullet), would developing a "super-hot" .380 round still result in case failure?

This is something that is dangerous and very novice, I understand, but still a curiosity.

My theory is that with the blowback action absorbing most overpressure in slide retraction, additional pressure would propel the slide faster than it would put pressure on the sides of the case, thus filtering much of the additional pressure out of the barrel and ejection port...or does the case still spend enough time trapped in the chamber to result in backpressure causing case-head failure/wall-failure?
