Perhaps one of the people whose servers were running out of callbacks
could tell us if the "looping trying to free a callback slot" behaves like
this. There's a fix in 1.2.7 but the right answer is to fix
viced/callback.c to not use u_short for storage of the callback index. No
one has gotten to it yet.
