    pipe - pre-MP work, remove direct map and sfbuf features
    
    To help with the initial MPSAFE work we are removing the direct-write
    optimizations.  This represents a slight nerf on a SMP box on a modern
    cpu, but not really enough to matter in the grand scheme of things.
    They may return at some future date.
