I wanted to say r+, but then I did an svn blame and found that r122505 changed this from copyfile to read/write.

There was more refactoring there, so this is probably still ok, but I didn't take the time to understand why. Would you mind figuring out and explaining it?

Ooh, good catch, it was so that the code to make the enclosing directory would be run. 

We should do that in this case too (but in this function directly instead of by re-using _write_text_file). I don't think Dirk's reasoning that reftests should use the same mechanism stands up, because we can (??) ensure that the test output is UTF-8 (since it is the output of WebKit), but can't do the same for the input.

Will fix, thank you for the observation :)
