The buffer is used in three places, part of the skinny device register process (basically once per device), a new call (every call), and skinny debug show cli (when used). The most likely cause of multiple threads accessing the buffer at the same time would be two simultaneous calls (on different devices), both of which would be using the same new buffer anyway.

Basically this stuff is purely for dev work, and personally i can live with the odd bit of garbage on the cli (only in dev mode) which would be preferably to something like adding locks which could result in slightly different functionality between dev mode and normal mode.

Happy to do the change, but not sure of the value added.
