Triggering huge-page collapse from user space

Think of the energy. It takes an release of energy to make things explode, a minimal flow of energy to make things collapse, while an implosion gives of a blast of energy.

So I guess collapse is the right word here. There's a minimal change observable from outside the system, while what was there is still there, just looking a lot smaller because all the empty space has been squeezed out.
