Comment:

 `$wp_roles->reinit()` calls `get_option` which uses `$wp_object_cache`, so
 it should be run after the cache object has been switched to the new
 blog_id. See attached patch.

 This actually also fixes the problem described in comment:26.

 I haven't been able to create a testcase to "prove" the issue, but I can
 attach a simple plugin which shows the problem, if needed.
