But note that my implementation allocates memory "on demand". If IPC syscall will not be used inside of jail memory will not be allocated. If think also that this will be trivial to add value to jail struct that will thell if we want separate IPC memory zones for this jail or not. +> Jail is not a true virtual machine. +> Let's keep it a *light* virtual machine replacement, with single IP stac= k, +> one memory zones for all jails and host, etc. I think it should be and it isn't now because of implementaion problems.
