The following problem occurs on my 64-bit Windows 7 system but not on my

I start the X server using the Start Menu shortcut [modified to add
-emulate3buttons] and a .startxwinrc with the following contents:
eval `dbus-launch --sh-syntax --exit-with-session`
xterm
Running ps in the resulting xterm window shows no dbus-launch or
dbus-daemon process. But I can give the same dbus-launch command in the
xterm window, and the processes start as expected. I'm attaching
cygcheck output and the XWin log.
My hope in reporting this is that the problem I'm seeing (and the
difference between XP and Win7) is somehow related to the emacs problem
I've been trying to solve:

P.S. You'll see in the cygcheck output that I'm running a Cygwin
snapshot; but nothing changes if I revert to cygwin-1.7.13-1.
I forgot to say that if I remove "--exit-with-session" from the command
line in my .startxwinrc, then a dbus-daemon process does start.
I tried modifying the X server shortcut to read
C:\cygwin\bin\run.exe /usr/bin/bash.exe -l -c '/usr/bin/startxwin.exe
/var/log/xwin/startxwin.log 2>&1'
as suggested in a different thread, but that provides no information. The
resulting startxwin.log is virtually identical (with minor differences) to
XWin.0.log.
In particular, there's no indication of what's happening when .startxwinrc is
processed.
There's no output because ~/.startxwinrc generates no output.
For starters, it would really be helpful if someone could try to reproduce my
problem on a 64-bit Windows 7 system. At the moment, I don't even know if
there is a bug somewhere or simply a problem with my own system. Here's the
recipe:
1. Create a .startxwinrc file with the following contents:
eval `dbus-launch --sh-syntax --exit-with-session`
xterm
2. Start the X server using the Start Menu shortcut.
3. In the resulting xterm window, give the "ps" command. If things are
working right, the output from ps should show a dbus-launch process and a
dbus-daemon process.
These processes do appear on my XP system but not on my Windows 7 system.
FWIW, it works on XP for me as well.
I tried with the following ~/.startxwinrc:
eval `dbus-launch --sh-syntax --exit-with-session | tee /dev/stderr`
xterm
... which at least lets you see the pid of the dbus-daemon that is started.
I'm not sure if --exit-with-session is correct with startxwin, since the
startxwin process will not linger after it has started ~/.startxwinrc, and I
don't know if stdin will remain open after it (and the process tree above it
waiting for it) exits. I have this vague recollection that 'run' has to do
different things on XP and W7, which might account for the different behaviour?
