On some hosting servers, the use of the /tmp folder is prohibited. Because of that, some errors are returned that obviously show that we should find an alternative solution. This seems to be limited to Doctrine, though:

I imagine there would be some available setting to allow Doctrine to use another folder (like app/cache/) but I don't know where it is and how we can properly change that setting without altering the vendor directory...
