Yes, understood.

However, your original statement that "You can't remove a coprocessor"
needed some clarification, in that the coprocessor that threw the exception
_is_ removed from the active set of coprocessors for that region.  So it is
no longer invoked for pre/post hooks on the call path for further requests.

Wei cared about.
