C:\WINDOWS>ruby -v
ruby 1.8.1 (2003-12-25) [i386-mswin32]

C:\WINDOWS>irb
irb(main):001:0> Process.fork {puts "I'm a child"}
NotImplementedError: The fork() function is unimplemented on this machine
        from (irb):1:in `fork'
        from (irb):1
irb(main):002:0> exit

Cygwin doesn't count.

What's against win32/popen3 being included in the one-click installer?

Cheers,
