Your program is most certainly non-deterministic, and you will sometimes
close a closed channel and panic. There is no thread safe way to test if a
channel is closed, then close it if it isn't.
I think of channel ownership in a similar way as of memory ownership in
C/C++. If this channel is being

ISTM that there are no guarantees about the behavior of that program at all.
Access to c from niller and closer is not synchronized, so it's not really
