It is difficult to debug kernel programs. That is one reason why user-level
Click is so useful. Also, the debugging methodology will depend on what you
are trying to debug....

Sure! What you describe will work. Push input ports (like Queue's input
port) can be connected multiple times. So you can say

   s1 :: XXXSource(...)
   s2 :: XXXSource(...)
   q :: Queue
   s1 -> q; s2 -> q
