The normal way to send out these patches is as three emails; a 0/2 cover
letter, 1/2 replying to 0/2 and 2/2 also replying to 0/2.  That's what
has Lorenzo confused.

You seem to not understand that there is disagreement on the semantics
of mseal().  I mean, ther's been a lot of arguing about that over the
last week.  There's understanable reluctance to accept a large pile of
tests saying "this just ensures that mseal behaves the way I think it
should", when there is substantial disagreement that the way you think
it should behave is in fact the way it should behave.  Be prepared to
argue for each semantic that you think it should have.
