The reason is that there is no direct equivalent of fork(). It is the
same in OS/2. If you wish to start a new process, you have to use
Windows or OS/2 specific system functions, exec in perl is just kind
of emulation. The fork() function is emulated in OS/2 in EMX and in
Windows in RSX but the Windows port of perl apparently does not make
use of RSX (and I never tried RSX in Vista).
