emacs-x11 takes 30-40 sec to open after upgrading to cygwin-1.7

I've followed this thread with interest, but so far I thought I'm not  
affected. I usually start emacs along with the xserver by typing  
"startxwin /usr/bin/emacs" in the MinTTY console. This works without  
problems. Also, starting Emacs from the right-click menu of the X  
server in the system tray works fine. However, I've never noticed that  
starting emacs from MinTTY into a running X session actually takes  
quite some time. That is, I can confirm this part of the OP's problem.

What I cannot confirm is that xterm works ok. xterm runs ok from the X  
server right-click menu. It shows the same start-up delay when started  
from MinTTY as emacs. Interesting, but not necessarily related to the  
problem is the fact that in both cases different bash startup files  
seem to be evaluated. When starting from MinTTY (and waiting...), I  
get my customized bash prompt, whereas I get a default "bash-3.2$"  
prompt when starting from the right-click menu.

BTW I don't have a ~/.fontconfig directory or an ~/Xdefaults file, so  
these are probably not related to the problem.

I used strace to see where xterm spends its start-up time, see the  
output below. I get several pages of the block of lines shown below.  
Each block takes a couple of seconds to finish, so this is where most  
of the time is wasted. Does this help to find out what's happening?

regards,
Markus
