Sorry, nothing mysterious is happening. My stupid helper macro  
includes a create-prefix-dispatcher call and a push to *dispatch- 
table*, so obviously it pushes something new to the *dispatch-table*  
every time I call it. Using a plain old defun to redefine an existing  
handler does exactly what it should – my problem was a confusion about  
how lisp works, not about how hunchentoot works, and I apologize for  
the noise.

Back to mucking about,
Eric
