It's also weird that it would be 35% slower over ra_svn. I mean,
shouldn't it be the same sequence of editor operations? The reporting
part shouldn't take any noticeable length of time.

(As an aside, I noticed recently is that ra_svn does a round trip per
property in your working copy. So if you have 100 files and 10 props
per file, that's 1000 round trips. Oops. That's because you have to
get the error status for each change_file_prop call and report it to the
caller before you can do everything else. I'm not sure if I should
propose an editor API change or just make ra_svn pipeline
property-setting behind the scenes and report property-setting errors at
close_file or close_directory time.)
