Comment (by innocuo):

 I was just replying, too :)

 @jorbin, as @dd32 mentioned, {{{global $wp_filter;}}} needs to be added
 within {{{wp_start_object_cache()}}}

 After doing that, your patch works OK.I tested the following cases:
 - if {{{object-cache.php}}} v2.0.6 exists
 - if {{{object-cache.php}}} doesn't exist
 - if {{{object-cache.php}}} exists and is an empty file
 in all cases, I don't have APC enabled. It looks like it should work if
 APC is enabled as then {{{object-cache.php}}} doesn't add anything to
 {{{$wp_filter}}}.
