Well yea. But given it's explicitly tied to aset.c that doesn't seem
like a sensible thing. DefaultContextCreate() or something (in mcxt.c),
which then calls AllocSetContextCreate, seems better to me.

Don't think aset.c is actually that good, so I'm not convinced of
that. And even if it's just to verify that a special case allocator
actually works with more coverage...
