in failure route the sip message is cloned in shared memory, with many
references to shared memory buffer, as well as shorter size (just to fit
the sip message) of the buffer storing the message (the core used a
private memory buffer to max capacity configured for message size).

Changing these shared memory references and buffers will be a lot of

If you intend to work on it, then make it configurable and in first
phase a compile time option with #define/#ifdef macros. Such change will
have a lot of effects, so it is better to have an easy way to switch on/off.
