Since my changeset a5efd5021ca1, the Python test suite starts to fail randomly. Running test_asyncio modifies sys.exc_info(): it is not (None, None, None) after the execution of test_asyncio. The problem comes from test_cancel_make_subprocess_transport_exec() of Lib/test/test_asyncio/

I tried to write a simple script which does not depend on Python to reproduce the issue. See attached script.

exc_info after except (<class '__main__.MyException'>, MyException(), <traceback object at 0x7f09201ad7c8>)
exc_info at exit (<class '__main__.MyException'>, MyException(), <traceback object at 0x7f09201abd08>)

exc_info is supposed to be (None, None, None), at least at exit.

I will try to write an even simpler script to identify the bug.
