+++ This bug was initially created as a clone of Bug #1122012 +++
Description of problem:
Currently, the permissions of the shared memory segment created by the SHM refclock are set from the unit number. Units 0 and 1 are created with owner-only access, units 2 and above have world access. This is a problem in applications where more units than two are needed and world access would be a security problem.
