No, this will not work. sys.path takes string. We can had a marker
like "__modules__" in sys.path then we add a Python loader in
sys.path_hooks for the marker. The new Python loader will read the
thread local variable from web2py (could be bended pretty much
anywhere). But I think this solution would be more complex then the
previous one I just described.
