:    Hmm.  I think we will have to use the serializer, actually, and
:    not a lockmgr lock, because a lot of that code runs from an

    Bleh.  I looked at it more carefully.  The sound driver is a huge
    mess.  Every little sub-driver has its own lock.

    I think we may have to use lockmgr locks after all.
