If there are others interested in this work, me and Alexander had a go at his
problem yesterday and together we managed to identify the problem and come up
with a fix for it. The attached 0001*patch is that fix.

I identified the same basic flaw in the sftp_write() code path and wrote up a
patch for that as well, as can be seen in the attached 0002*patch.

I'm interested in feedback on both how they work in reality but also on the
actual technical subtleties.

I am especially aware that this logic needs better comments/documentation to
make us less likely to re-introduce similar problems again in the future!
