Removing DeferredHandler and using a simple Handler to post callbacks
DeferredHandler was added when we were posting each icon separately,
to prevent starvation. But since then we have moved to binding batct
items during bind.
Also fixing waitForIdle not waiting the second time. waitForIdle was
using a global variable to maintain state, and was not waiting properly
when its called the second time before binding deep shortcuts
