Comment:

 Changes seem fine.  I do have one question:

 Is the equality test used in getCalloutHandler sufficient to consider the
 two packet pointers equal?  As these are shared pointers, this amounts to
 a.get() == b.get(), which would compare the allocated pointer values,as
 opposed to *(a.get()) == *(b.get()) (if the packet classes had ==
 defined)?  Basically, is there any risk that in procesing a packet, we
 throw it what was allocated and replace it midstream?   If not, then this
 should be fine, but maybe worth a comment?
