I ended up using this web2py testrunner:
http://pythonhosted.org/web2py_utils/test_runner.html
This runs each test in it's own local environment.
Most things now work. But there are still some things that do not work.
I'm not getting any of the already mentioned exceptions but just an
exception specific to the code tested.
It's strange because when i execute the exact same code from a controller,
it does work.
hard to debug also because i can't reproduce it via a controller call and
the details about the exception obscured by "RestrictedException"...
Anyway, i think your solution is very clever.
maybe i'll set something like that up for the tests that fail to run
otherwise...
But i've not given up yet...
