Add and use and unlikely-to-be-eliminated memwipe()
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.
