This article shows a 3x speedup for thread creation over fork(), not the
numbers you have quoted. Furthermore, it talks about Linux kernel 2.0.30.
Do you know how old that is? The paper itself comes from Linux Journal,
January 1999, according to the author's web site.

Argument will get you nowhere - if you want it done then do it and prove
everyone wrong.
