That's what I suspected.

If it's a useful feature on Unix, it's useful on Windows, too. If that's
the case, then we should look for the root of the "problem" (ignoring
the fact that performance measurements show it isn't one):

Windows filesystems don't allow deletion of a file if it's marked read-only.

Well then, the solution seems straightforward: Add an option to
apr_file_remove that will force the deletion even when the file is
read-only. That's a no-op on Unix and a chmod on Windows (and probably
OS/2 and Novell).
