Thomas Grainger <tagr...@gmail.com> added the comment:
there could be multiple messages here
perhaps it could be:
```
finally:
# Must reacquire lock even if wait is cancelled
cancelled = []
while True:
try:
await self.acquire()
break
except exceptions.CancelledError as e:
cancelled.append(e)
if len(cancelled) > 1:
raise ExceptionGroup("Cancelled", cancelled)
if cancelled:
raise cancelled[0]
```
