    Add and use and unlikely-to-be-eliminated memwipe() · 49dd5ef3

    Apparently some compilers like to eliminate memset() operations on
    data that's about to go out-of-scope.  I've gone with the safest
    possible replacement, which might be a bit slow.  I don't think this
    is critical path in any way that will affect performance, but if it
    is, we can work on that in 0.2.4.
    Fixes bug 7352.
