State-Changed-Why:
    The root issue here is related to PR/5820.  If someone
    on a Linux platform could *please* just try my suggested
    fix (which is already used on platforms where it is not
    legal to seek on interactive streams), then this whole
    seeking performance problem will go away entirely for
    you...  See concurrent post to libstdc++ mailing list.
