Subject: sorta fixed bug with sleep and timing where interrupting dwmblocks by
 clicking on the bar would interrupt the sleep causing it to reload everything
 sooner than it should, which would cause slower things to not update and
 disappear untill they were reloaded. This was especially a problem with using
 scrolling on blocks.  Still occasionally breaks but is much less horrible.
