This reverts commit 05745bbd. Whenever the busscanner runs, which happens each time a DSM joins/leaves, the modelmaintenance thread will nor process model events. This is extremely annoying on startup, since the administration UI complains about the DSS not running, which is running, just not responding to the web requests, since they are stucked in the model barrier. Also on dss11 sd-card, with legacy jffs2, this is quiet annoying since the ds485d regularly hangs and loses bus conection
