This may be a case of incredible bad timing, as I haven't kept up
on the development of the pdumper. Doing some light reading up on
it now, it seems to me that it does the loading from a custom file
format instead of writing a native executable.
Evidently, this renders any improvements on the unexec code moot,
although it's still in the tree, I guess for platforms where the
pdumper is not yet fully tested, so I understand the reluctance to
spend any more scarce time on it.

Yes, although one could discuss if the concept of ported/unported
status still applies in the same way once there is the pdumper.
