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.
