PydocUrlHandlerTest.test_url_requests() of test_doc checks "search?key=pydoc" URL. This operation has to load all Python modules to get their documentation. The problem is that loading all modules can have border effects with other tests. The most recent example: test_signal fails if it runs after test_pydoc. test_pydoc imports _tkinter and _tkinter loads the Tcl library which creates a thread waiting events in select(). The problem is that test_signal supposes that there is only one running thread.

Can we run tests loading all modules in a subprocess?

I have a fix to test_signal, so this bug is not really blocker, but it's better if a test doesn't touch the environment too much.

To see which modules are imported by pydoc, you can use:
import pydoc; pydoc.ModuleScanner().run(lambda *args: 0, 'XXX')
