Yes, it's much the same in most virtual-memory Unixes. No decent virtual-
memory implementation will insist on reading the whole thing in first,
unless perhaps the program is too small for demand paging to be sensible.
Most of the general techniques you mention can be found in any good
virtual-memory Unix. Details and policies differ.
