Comment (by bigdawggi):

 Uploaded a new patch to address the following:
 === Issue ===
 If you switch to the current blog id, while in a nested switch_to_blog,
 the restore_current_blog() calls, don't match up, and give an incorrect
 blog id at the end.

 === Resolution ===
 - switch_to_blog() function:
     - If you're switching to the same blog id, set the right vars to show
 that you've switched, do any attached switch_to_blog actions, but return
 before doing the heavy-lifting in the function (being that that has
 already been done for this blog, by the previous switch)

 - restore_current_blog() function:
     - Removed the check for the same blog id, so that whenever the
 restore_current_blog function is called, it always pops an item off the
 $switched_stack array.
