With pstree I see:

-+= 00001 root /sbin/launchd -v
  \-+= 00481 windowse /System/Library/Frameworks/ 
ApplicationServices.framework/Frameworks/CoreGraphics.framework/ 
Resources/WindowServer -daemon
    \-+- 06548 pete /Applications/MacPorts/X11.app/Contents/MacOS/ 
X11.bin -psn_0_36306945
      \-+- 06569 pete /bin/sh /opt/local/bin/startx
        \-+- 06606 pete xinit /Users/pete/.xinitrc -- /opt/local/bin/ 
X :0 -nolisten tcp -dpi 100 -auth /Users/pete/.serverauth.6569
          \-+= 06609 pete /bin/sh /Users/pete/.xinitrc
            \-+- 06630 pete /usr/local/bin/emacs-23.0.90 -geometry  
100x57+696+145 -T 23.0.90 --debug-init

So it seems that theory and practise meet. Examining with ps the  
processes' environments I get these PATH values:

• 00001 root /sbin/launchd -v	does not seem to have any
• 00481 WindowServer		has PATH=/usr/bin:/bin:/usr/sbin:/sbin
• 06548 X11.bin			has PATH=/Users/pete/bin:/usr/bin:/bin:/usr/sbin:/ 
sbin:/usr/X11R6/bin:/usr/local/sbin:/usr/local/bin:/sw/bin:/usr/local/ 
bin:/usr/texbin:/Users/pete/bin/FDK/Tools/osx
• all other programmes in the chain ínherit this (no quartz-wm running)

This is a path that is not derived from any of my supported shells  
(sh, bash, csh, tcsh). And it isn't root's path, not even when I  
(root) copy my ~/.MacOSX directory to /var/root.

When I change /etc/csh.login to contain /usr/local/texlive/2008/bin/ 
universal-darwin instead of Mac TeX's silly /usr/texbin, the latter  
is substituted with /usr/local/texlive/2008/bin/universal-darwin.  
Nevertheless elements from my shell's path value, coming directly  
from ~/.MacOSX/environment.plist, are not part of X11.bin's  
environment. They're included in all other Aqua clients, for example  
Carbon Emacs or Emacs.app or ...
