fork() and kill() is just as OS specific as Win32::Process is. One just got a builtin, the other did not. One presents itself as if it was general, the other says clearly it's OS specific. If you wrote a list of caveats from the point of a Win32 developer it would be just as long. And would list the same things, just with different wording. fork() is not THE or even THE ONLY way to create processes, it's THE UNIX way to create processes. > Then start to look at what > modules simply won't work on Win32 due to the lack of supporting > libraries. If you start your development on Unix, you notice the modules that work under Unix and do not under Win32 and never even notice those that work under Win32 and not under Unix. Besides, those that are Win32 specific prettymuch always say so in the name. The unix ones do not bother.

I've moved between California, Colorado, Kansas, North Carolina, Massachusetts and probably I couple I am forgetting and never had to change anything but a few addresse for snailmail. I have also visited France and it was an uphill fight. My gosh them bastards speak french!
