Only when they are used, in which case so do SVR4's - you just see it in a different place, namely the user process. If the kernel is taking up the memory the user isn't free to do so as well, so it must page. So when SVR4 grows a table (or whatever, I've not seen the kernel sources yet), it deprives a user process of available physical memory which must then be backed with paging store. When AIX grows a table the same thing happens - except it is the kernel table that gets backed (except when it is paged in, and then all bets are off ;-). -- John F.
