Agree, some old ideas like swapping quickly rot away by new DRAM technology,
RAM is so cheap, writting code for high speed swapping system? how fast 
will a
machine be when doing heavy swapping ? this is a joke. Also in Embedded 
system,
there is no swappping device, writting code for nothing only wastes time.
We already have abliity to swap out user space memory,  I think that's 
enough in
most cases.
