Clojurians Log v2

Sorry if this has been addressed many times before, I was having trouble turning up anything in my search: If a exception is thrown inside the thread started by (a/onto-chan!! ch lazy-seq-with-io) is there a good way to handle it? The code for onto-chan!! is small enough that I could replicate it with a new ex-handler parameter, but I wanted to check that i wasn't missing something obvious.
