The process is apparently a native Windows process.  I don't know why it
shows up twice when started from bash but since it's a native process,
Cygwin's kill will not work as expected on it.  1.3 is long gone, and
things have considerably changed since then.  I don't know the exact
difference, but kill() is supposed to send a POSIX signal, which native
applications have no idea about.  You should rather use the native
taskkill command to kill native processes.
