Subject: Refactor code from tenthSeconds to doEveryTenthSeconds

A preparation for timer coalescing: tenthSeconds is just a sleep whereas
doEveryTenthSeconds enables using a central timer and waiting for all
monitors to update before refreshing the window. This commit is just a
simple refactor, the actual timer coalescing code comes later.
