Merry Christmas Lai,
Here is how to deal with it :
- Allow iterators only in the following cases :
- non-overwrite channel
- writing is stopped (paused) in overwrite channel
- _Never_ allow iterators on overwrite channels with non-paused writers.
That's the only scenario which can corrupt a channel due to a writer
push.
Best regards,
Mathieu
P.S. I'll be on vacation and probably unreachable until January 2nd.
