This just made me look again at the abuf implementation itself and
become filled with regret I didn't reject it back in 2021. We're
introducing wrappers around standard functions and calling conventions /
patterns with something homegrown (and so not intuitive to others) that
mainly hides the "sysmem" challenge we also have and I wish you were
interested in revisiting how that part of sandbox works instead. And
even if this is a better design, for the sake of argument, it's not
something everyone else is used to. And that's important.

If we *really* need something different / new here, I'd rather see us go
and wrap common/dlmalloc.c with kmalloc/kfree/etc and so give people
something even more familiar-looking.
