One thing could be a problem with demand-loaded executables: finding
the page on disk means going through the file system, whereas paging
from a dedicated swapping partition could be a simpler and faster
operation. Admittedly, the first read must be done from the
executable, and demand loading from the file probably makes the load
process seem faster.
