while at it, maybe we can get rid of the additional copy after
successful transfer, and try to do "the same" as rsync, namely
defaulting to a temp file in the same directory.

then after successful transfer, try to rename, fall back to copy,
fall back to create/truncate/read from tmpfile write into new file.

see rsync code for what I mean.
