It should be the same as in the previous call.  But that can be relaxed
-- we could say that the mech must keep an internal copy if it will
continue needing it after the first call.

If it's hard to track them you can always place them in the callback
function's argument -- a void * that would be a pointer to a struct with
all the context that the callback needs, including those GISC args if
you're not storing them elsewhere.
