You're looking in the wrong place.  Take a look at win32.c, which is
where Process.kill is defined for Win32.  The only named signals it
understands are SIGINT and SIGKILL.  It looks like any other value
returns Errno::EINVAL.  Not a great implementation IMHO.

Note that win32-process includes a nicer version of Process.kill.
