paging/swapping isn't necessarily going to occur simply because there
could be clean, unref'd pages that'll get tossed well before you'd bother
paging. It's not clear-cut from a given instant in time how much you'd
have to allocate to really force paging.
That said, there is a getconf param for available phys pages
% echo $[ $(getconf _AVPHYS_PAGES) * $(getconf PAGE_SIZE) / 1024 ] KB free
4804 KB free
might get stuck parsing /proc/meminfo otherwise.
