This fixes an issue where the mUpdateSeekBars runnable was being repeatedly posted to the handler while keeping a reference to the transport control (and hence keyguard). Even after the view was detached from keyguard it would continue to post events that would ultimately keep the instance of keyguard from being GC'd and cause keyguard to slow down.
