It turns out the restarter didn't really work on Win32. This checkin
adds a hacktastic Win32-specific restarter that uses Proc::Background
(which uses Win32::Process) and actually works.

You won't get any of the benefits of the new restarter code on Win32,
since it reloads everything on every restart, but it does actually
seem to work, and it's not any worse than the old version.
