RE: Why does svn want to write files to .svn/tmp for read-only operations?

It's puzzling that this isn't done with pipes, or with in-memory
processing. With an external diff, I suppose you might need one temp
file (though not two) but the internal diff engine should do all this
on the fly.

On the other hand, none of that explains why a temp file is created
for a status command. Quite apart from being a nuisance when people
don't have write access to the working directory, I would expect that
an in-memory solution would be a whole lot faster, since it doesn't
have to create, write, read, and delete temp files all over the place.
