The "expensive" argument is also why the Windows API has no fork,
although the Windows NT-kernel supports it. (There is even a COW fork in
Windows' SUA.) I think fork() is the one function I have missed most
when programming for Windows. It is the best reason to use SUA or Cygwin
instead of the Windows API.
