We had long discussions on several Mailing lists over the years to
check what VirtualLock really does.  The conclusion is that it does
not work in the described way.  See Peter Gutmann's article on the RNG
or his book.

Recently some newer information might change the picture but tehre is
still no agreement.

No, it won't appear in GnuPG unless there is a portable and working
way of doing so.
