Does the permissions limitation apply to Linux (CentOS) and shared mutexes
or segments created by other users or root?

I have a mutex in the /dev/shm folder created by another user with these
permissions (from ls -l):
-rwxr-xr-x 1 webers users        160 Jul  1 15:24 Lookup_Mutex

My user account is a member of the users group, but since it defaults to
just read only access I can't actually use the mutex as a mutex.  Is there
any way to get around it?

Thanks,
Matt
