was executing and generating a new extension for another channel that starts out where the

copying a few basic pool-allocated structures from one channel to another there really is
not much to worry about here in terms of threading since we use read-write locks.
While the features are nice, they only really are needed in one specific crazy attended
transfer scenario where one channel was in the middle of calling a particular extension
