no doubt about this :)  sidenote: i think we need to a
bit more restrictive or specific about "conftest.py" usage
... note btw, there is "--traceconfig" where py.test shows which
conftest.py files it uses.  

Most confusing is: "globally" importable "conftest.py" are imported
in a mangled way - thus the module that py.test sees as a tool 
is not identical to the module you get from a global "import conftest". 
This can lead to subtle problems.   The reason for this "mangling"
of global conftest.py files is that there are real life uses 
of multiple global conftest's (e.g. one of them residing in 
Armin's home directory globally configuring py.test to use 
his hacked RXVT terminal and then e.g. the pypy-dist/conftest.py 
file etc.).  I am still wondering on how to best simplify 
the situation.
