I thought, you would say that ;-)

You are right, -mpreferred-stack-bound might have been a way
to get rid of the extra stack padding.  However, AFAIK
getting rid of the stack padding means slower code, doesn't
it.  Maybe doesn't make that much of a difference, because
GHC code doesn't use the system stack much, but still...
