I doubt that demand paging is good idea in many cases. What about
adding a flag to executable that it should be lineary loaded? Small
utilities (where almost all code is used) will benefit from this.
And now it seems that even fat executables (where on-demand loading
should be major win) are better loaded lineary...
Are there any benchmarks of on-demand vs. linear load available?
