well designed machines do NOT swap and have not alligend
swap at all - in the case of virtualization you MUST NOT
enforce swapping if you really like perofrmance

even in 100 years there will be installations of people
having 50,80,100 or more vurtual machine son a host and
try to allocate only needed ressourcs

wasting RAM a a default is only bad in such cases

but however, since most packagers starting to move all
their temp stuff to /var/tmp we well not noitice any
changes except that you have to mount the tmp-vdisk
to /var/tmp istead /tmp
