 Not exactly. I said that you have to alocate the dst vector in a CycleBuffer
if you want your program to run on a multicpu machine.
 Also, you can tell performer to do a fast pointer swap instead of a copy of
the Buffer when synchronizing the CycleBuffer by using the pfCBufferChanged()
API

 Yes, but it's not so useful

 It is quite unexpected on a single cpu machine. I have no guess
