Well, it's software, so anything is _possible_, but I'd rather not do
that, because it creates artificial differences between the
(speed-critical) local unwind case and the remote unwind case.
Furthermore, the unwind table is of a known size, relatively small,
and accessed fairly randomly (via binary search), so it is normally
preferable to read the table all at once and I'd rather design the API
for this common case.
