Just for context, Bo Gan has already posted a solution for emulation to
use a small fixed (relative to VLEN) amount of stack for the mask [1]
(depending on other fixes [2]), so this "some other day" should happen
soon (knocking on wood).

My personal preference is to not to further complicate the code in the
mean time, so I don't think the heap allocation solution is really
necessary. But if bumping the stack size is not acceptable then heap
allocation is probably the way to go, although that would still be a
temporary solution.
