Comment (by rmccue):

 We changed our object cache implementations to hijack `alloptions`
 ([https://github.com/humanmade/memcache-object-cache/blob/master/object-
 cache.php#L153-L231 Memcache] and [https://github.com/humanmade/wordpress-
 pecl-memcached-object-cache/pull/1 Memcached]).

 The problem with this approach is that it's pretty terrible handling
 without WordPress helping out more. The object cache receives an opaque
 heap of data that then needs to be parsed back out, diffed, and saved
 correctly.

 There needs to be changes in WordPress core for this. I can't remember the
 exact approach we discussed, maybe @joehoyle can.
