I'm seeing performance problems in emacs when started via the new 
run.exe under X.  I have a desktop shortcut whose target is

   D:\cygwin-1.7\bin\run.exe D:\cygwin-1.7\home\kbrown\bin\startemacs.bat

Here startemacs.bat is:

$ cat bin/startemacs.bat
@echo off
SET DISPLAY=127.0.0.1:0.0
SET CYGWIN_ROOT=\cygwin-1.7
SET RUN=%CYGWIN_ROOT%\bin\run -p /usr/bin
SET PATH=%CYGWIN_ROOT%\bin;%PATH%
%RUN% bash -l -c /usr/bin/emacs&

I'm running XP SP3.  To reproduce the problem:

1. Start the X server by using the start menu shortcut (which invokes 
run.exe on startxwin.bat).
2. Start emacs by the shortcut above.
3. List the home directory via C-x d [RET].
4. Repeatedly press the space bar to scroll through the list.  There is 
often a delay before the cursor moves.

Reverting to run-1.1.10-1 solves the problem.
