I don't like this idea.  I'd bet that the UI thread already has a 
handler; it seems the intelligent thing to do.  And I'd bet too that the 
handler for the UI is publicly available, in some publicly documented 
API.  And I'll further suppose that they called the public method to 
access the UI handler "runOnUiThread".

So don't do this, because you're just reinventing a perfectly good wheel.
