Samba not using my RAM for shared memory?

The Samba v2.0.4b doc says:

  share modes (S)
    These  open  modes  are  not  directly supported by
    UNIX, so they are simulated using shared memory, or
    lock files if your UNIX doesn't support shared mem-
    ory (almost all do).

Yet I have these files on my (RedHat v6.0 / kernel v2.2.10) system:

# ls -l /var/lock/samba
total 12
-rw-r--r--   1 root     root      1048576 Jul  8 14:51 SHARE_MEM_FILE
-rw-r--r--   1 root     root           12 Jul  8 14:53 SHARE_MEM_FILE.processes
-rw-r--r--   1 root     root         4000 Jul  8 14:57 STATUS..LCK
-rw-r--r--   1 root     root          231 Jul  8 16:49 browse.dat
-rw-r--r--   1 root     root           20 Jul  6 18:41 nmbd.pid
-rw-r--r--   1 root     root           20 Jul  6 18:41 smbd.pid

Note that file SHARE_MEM_FILE is 1MB in size, the same as the default size
("shared mem size") as the shared memory.

Does this mean that Samba is *not* using my system's RAM for tracking file
use?  And if not, why not?

Thank you.
