This is done to reduce a copy after the dictionary's binary content is received from RPC. The 'extra_free' flag is used when we use a GF_*ALLOC()'d buffer in protocol to receive dictionary, and extra_stdfree is used when RPC itself allocates the buffer and hence uses 'free()' to free the buffer. > I think this is not needed anymore.

We are not using dictionary itself as protocol now (which we did in 1.x series though).
