This failing test is a nasty one - the whole thing just hangs (so I imagine Travis will run for a while before hopefully giving up). Here's what happens if I add --full-trace and then hit Ctrl+C to cancel a test run: ``` $ pytest -k test_execute_write_fn_block_true --full-trace =================================================================== test session starts =================================================================== platform darwin -- Python 3.7.5, pytest-5.2.4, py-1.8.1, pluggy-0.13.1 rootdir: /Users/simonw/Dropbox/Development/datasette, inifile: pytest.ini plugins: asyncio-0.10.0 collected 410 items / 409 deselected / 1 selected
