  That change was intended to support vmware3, but
  wantrem parameter is useless because vmware3 uses SYSV shared memory
  to talk with X server and X server is native application.
  The patch worked because check for wantrem was not valid
  (wantrem and SHMSEG_REMOVED was never checked for SHMSEG_ALLOCATED segments).
  
  Add kern.ipc.shm_allow_removed (integer, rw) sysctl (default 0) which when set
  to 1 allows to return removed segments in
  shm_find_segment_by_shmid() and shm_find_segment_by_shmidx().
