Comment(by nacin):

 show_message() is specifically for the upgraders. Upgrading can take a
 while, and we deliberately call show_message() to write information to the
 browser updating the user on the status of the upgrades, as the package is
 downloaded, unpacked, etc.

 From what I have gathered from dd32, the original intention of
 show_message() was to send output to the browser. Not including a flush()
 here was an accidental omission when the upgraders were written.

 Hence why we should flush here even though we don't anywhere else in core.
