I ran my same test watching free and also watching shared memory segments as you suggested. I still see the 4k loss with free, but my shm stays constant. Here is the output of ipcs in case it helps.

------ Shared Memory Segments --------
key              shmid      owner    perms     bytes      nattch     status
0x00004746 0             root      777        2304       0
0x00004743 32769      root      777        2048       0
0x00005244 65538      root      666        65768     3

------ Semaphore Arrays --------
key              semid   owner    perms     nsems      status
0x00004747 0          root      777        1
0x00004744 32769   root      777        1

------ Message Queues --------
key              msqid    owner    perms    used-bytes messages
0x00005245 0          root       666        0            0
0x00005246 32769   root       666        0            0

Did you check the shm memory? (ipcs command)
