 Yesterday I was updating a test site (from 4.1.x to 4.2.x) using update-
 core.php  and I accidentally clicked 'back' button during installation,
 which aborted the update process when it wasn't finished yet. This
 resulted in breaking the site completely (call to undefined function wp()
 ). It could have been easily prevented by simple beforeunload prompt.
