in order to free the shm-segment you will have to destroy ALL references to it (read: all [pix_share_read] and [pix_share_write] objects referencing the same segment)
and quitting pd might _not_ free the shm-segments, since the destructors of the objects are not called. (which is a pd bug).
you either have to "properly" close the pd-patch or free the shm-segments with an external application (on linux (and afaik some bsd's) this is "ipcrm", probably on osX too)
