   Not that easy... Because the exechook() is called too late [after
   the uvm space is switched to the one of the new image and we need
   to destroy the shm space before that is gone].
   Also there is the issue of when to destroy the shm space... I don't
   think that the rest of the kernel has enough knowledge to do this.

ok.  i still want to turn sysvipc into LKM's.
i'll start looking at the issues.
