 Replying to [comment:5 johnjamesjacoby]:
 > 19500.2.diff moves clean_user_cache( $id ) ahead of the queries that
 delete the user in wpmu_delete_user(). Without this, calls to
 wpmu_delete_user() do not successfully clear the user cache because the
 user no longer exists. This causes...

 never cleared.

 #20460.

 Also Ryan on #19490: "We usually clean [cache] after the delete" because
 of possibility of actions firing in between. Doesn't look like an issue in
 this case, but something to think about.
