It's worse than that; I just discovered today (I *think*) that ever
regular props aren't being written atomically.

I mean, I know that when the update editor receives normal user props,
it stores them (along with new text) in SVN/tmp/, and then a log file
is executed which atomically moves the new text and new props into
text-base/ and prop-base/. But when the user runs plain old "svn
propset foo bar A/mu", there's no atomicity. We read the propfile,
change it in RAM, then write it out again. Oops!

I should put this on my todo list.
