Description
TrioPG (trio wrapper of asyncpg based on trio-asyncio) is crashing on windows:
fut = <Task cancelled coro=<BaseEventLoop.create_connection() done, defined at C:\Python36-x64\lib\asyncio\base_events.py:681>>
timeout = 60
@coroutine
def wait_for(fut, timeout, *, loop=None):
"""Wait for the single Future or coroutine to complete, with timeout.
Coroutine will be wrapped in Task.
Returns result of the Future or coroutine. When a timeout occurs,
it cancels the task and raises TimeoutError. To avoid the task
cancellation, wrap it in shield().
If the wait is cancelled, the task is also cancelled.
This function is a coroutine.
