Mmmm ... good question. Maybe we could only make the lock free logic 
(i.e. buffer and data) type-unsafe and keep the rest typesafe. The 
BufferLockFree<T> could then provide with the 
allocation/deallocation/copy to the type-unsafe GenericBufferLockFree. 
As far as I understood, that is the part that takes ages to expand, right ?

As usual, the main problem with fallbacks is that templating *needs* to 
be instanciated :(
