2a) By default, only 4MB of shared memory is supported by BSDI. Keep in
mind that shared memory is not pageable. It is locked in RAM.
The shared memory parameters are:
#define SHMMAX /* max shared memory segment size (bytes) */
#define SHMMIN /* min shared memory segment size (bytes) */
#define SHMMNI /* max number of shared memory identifiers */
#define SHMSEG /* max shared memory segments per process */
#define SHMALL /* max amount of shared memory (pages) */
