Which of the many flavors of spawn are you using on Win32? And how does
it work on Unix?

With 1.9 feature:

  $ ruby -v -e 'pid = spawn("cmd.exe"); sleep 3;
Process.kill("TERM", pid); puts; p Process.waitpid(pid); p $?'
  ruby 1.9.0 (2005-04-22) [i386-cygwin]

Which? I just use built-in method, and it works on other
platforms almost too, except for DJGPP and a few.
