Comment (by David_Rothstein):

 I was also thinking that it may be a good idea to combine this approach
 with the addition of the wp_suspend_cache_addition() call.  This is for
 two reasons:

 1. It looks like a good use of wp_suspend_cache_addition() anyway, due to
 the documented purpose of that function.  (Adding a bunch of temporary
 previews to the cache is kind of a waste.)
 2. If there are plugins out there that cache their output in the same way
 the WordPress core plugins did, they would still experience this bug until
 they fixed their code.  Using wp_suspend_cache_addition() is a good backup
 for that.

 However, for 2, I looked at the code in
 http://wordpress.org/plugins/memcached and it doesn't currently check
 wp_suspend_cache_addition() at all before putting things in the cache...
 so without updating that plugin that approach doesn't look like it will
 actually do anything to fix the original bug?
