hi, 

When I start emacs (alternated to emacs-X11) with `run emacs' on the
Windows console (started with the Cygwin.bat shortcut), the emacs
performance is not good (moving the cursor up/down is not smooth), and
not stable (hang/crash sometimes).

But if started directly with `emacs' or from the Start Menu shortcut of
emacs (C:\cygwin\bin\run.exe -p /usr/X11R6/bin emacs -display 127.0.0.1:0.0),
then all is good. Also good if started with `run emacs' in a
RXVT/PUTTY-CYG console.

One difference I see is the /proc/`emacs pid'/fd, in the former way,
there is only one fd:

    lrwxrwxrwx 1 bhj None 0 2006-12-01 08:00 0 -> socket:[1608]=

I believe this fd is the connection to X server; if started otherwise,
the fd list is:

    lrwxrwxrwx 1 bhj None 0 2006-12-01 08:00 0 -> /dev/console
    lrwxrwxrwx 1 bhj None 0 2006-12-01 08:00 1 -> /dev/console
    lrwxrwxrwx 1 bhj None 0 2006-12-01 08:00 2 -> /dev/console
    lrwxrwxrwx 1 bhj None 0 2006-12-01 08:00 3 -> socket:[1624]=
    
or with /dev/console changed to /dev/ttyN.
