This problem does NOT exist for Mod_python Servlets.  The servlet
handler does not use python's import system, instead it compiles each
servlet using execfile and the results stored in a cache, indexed by
servlets' full pathnames.  So, if I have two servlets:

  http://localhost/foo/index.mps 
  http://localhost/foo/bar/index.mps

and my document root is /var/www/html (so, directory /var/www/html/foo
is configured to use mod_python.servlet as a handler), then the cache
would have:

  '/var/www/html/foo/index.mps' : <instance of mod_python.servlet.Servlet>
  '/var/www/html/foo/bar/index.mps' : <instance of mod_python.servlet.Servlet>

Subsequent requests will look in the cache before compiling, so the
correct servlet will be found.
