Comment (by jtclarke):

 Hey -- sorry I somehow wasn't getting requests for feedback.

 The way I saw this was that on the sites I manage (MU with Batcache /
 Memcache), some (but not all) of the images were not being served
 correctly when Batcache was enabled and memcached was turned on.  For
 example, I would see all of my post thumbs, but not the site logos (site
 logos being extensions of the theme).  All files are uploaded via the
 uploader and served via ms-files.php.

 I too am surprised nobody has encountered this before.  Technically, the
 only way you would see problems is using 3.0 multisite (which uses ms-
 files.php and SHORTINIT) with Batcache/Memcache  -- but I can't imagine
 we're the only ones doing that.

 I still wish I had more concrete steps to reproduce -- It's unclear why it
 would affect some files and not all.  But I know that the problem was
 fixed if I turned off SHORTINIT -- which led me to dig deeper into the MU
 code and the placement of register_shutdown_function.

 Let me see if I can track down what, if anything, is unique about the
 files that weren't serving correctly.
