Just found that there more modifications needed. Big chunk of shared memory (2GB
or more) won't deallocate properly because "shmid_ds" structure has int type for
"shm_segsz" field. So, will need to change in sys/sys/shm.h (and
/usr/include/sys/shm.h), sysv_shm.c (there is shmid_ds's definition too) and
usr.bin/ipcs/ipcs.c source ("%12d" -> "%12ld" in line that prints segment size
information).
