That last sentence is a bit misleading as it implies that
H_SVM_INIT_DONE causes us to unregister the memslots with the UV,
which is not the case. Shouldn't it be "As part of H_SVM_INIT_START,
register all existing memslots with the UV"?
Also, do we subsequently communicate changes in the memslots to the
UV?
Paul.
