gentoo-overlay/dev-db/mytop/files/mytop-1.6-global-status.patch

Use GLOBAL STATUS instead of implicit session status.

As of MySQL-5.0.72, many of the status variables split for session and global
variants. Importantly, the Com_* and Questions ones did, and this broke the
statistics at the top of mytop.
