Those patches against FreeBSD 4.x (18 Feb 2003) provide as follows:
	- private memory zones for main host and every jail,
	- ipcs(1) is no more set-gid on kmem group, because it doesn't
	  use kvm(3) library,
	- added systcls:
		+ kern.ipc.msginfo - returns field msginfo from its jail
			struct or from main host if not jailed,
		+ kern.ipc.sema - returns field sema,
		+ kern.ipc.seminfo - returns field seminfo,
		+ kern.ipc.shmsegs - returns field shmsegs,
		+ kern.ipc.shminfo - returns field shminfo,
	- sysctl jail.sysvipc_allowed is set to 1 by default.
