Yes, the dissector for a given protocol layer calls the dissector for 
the next protocol layer up - and it's done through "dissector handles" 
which lets us centralize some functions (e.g., disabling dissectors), 
but adds some additional procedure call layers, as does use of internal 
routines to share code for different code paths, and as does the 
centralization of the "look up the dissector for a given selector value" 
(such as a port number) function.

I.e., it *is* a deep stack, but I don't consider it a problematically 
deep stack.
