In a sparse working copy of the Subversion codebase (/trunk,
/branches/1.6.x, /branches/1.5.x, and /site), here's how the cost of a no-op
svn switch (to the same URL and revision) -- which makes use of this
invalidate_wc_prop callback -- compares:

             1.6.x 1.7 (before) 1.7 (after)

ra_neon | 2s | 15s | 2s |
