Hi Rik,
good catch - I completely forgot to check the initialization

Looking closer at newary, I suppose that it should be
possible to move those other initializations before
the call to ipc_addid. That would likely get rid of
the problem, too.
However, I also see this line in newary, and I have
no idea what protects that data:
ns->used_sems += nsems;
It should be sem_ids.rwsem, and at least according to the documentation
both freeary() and newary() hold it.
