One one clarification to make on Kevin's email. (I was in the process
of answering this myself =))

In general cb_check is the only function that acts on callbacks. However,
depending on how you implement your proxy, you may want to use cb_add
or cb_free outside of cb_check. I can think of at least one case
off the top of my head where you could use cb_add outside of cb_check.
