If a .pth file contains a valid directory, it is added to sys.path but  
it's not searched for additional .pth files. From  
http://docs.python.org/lib/module-site.html

	"A path configuration file is a file whose name has the form package.pth  
AND EXISTS IN ONE OF THE FOUR DIRECTORIES MENTIONED ABOVE" (emphasis by me)

(the four directories being .../lib/python2.5/site-packages, site-python,  
etc.)

(Mmm, what the 2.5 docs say is not exactly the same as the actual code in  
site.py, and the version in http://docs.python.org/dev/library/site.html  
is not the same as the svn version of site.py... anyway, directories added  
by mean of .pth files are not recursively searched for more .pth files)
