Works fine for me, albeit using kill -9, not regular kill. What
exactly do you see? According to a message upthread, Emacs hangs hard
any time you try to open a dialog box. Can you please attach gdb to
Emacs when it's in this state and get a backtrace?

If these problems persist, my first instinct would be to not support
dbus in cygw32 builds of Emacs. People mostly use dbus to integrate
components of a Unixish desktop environment, and I imagine users of
cygw32 want to use Cygwin Emacs as part of a Windowsish desktop
environment, which uses USER32 facilities to do what other
environments do with dbus.
