Hi Artyom,

It works!  Specifically, I ran:

  guix shell guile guile-ssh \
    --with-branch=guile-ssh=wip-fix-channel-leak -- \
    guile ssh-channels.scm

and the script (same one as before) ran several hundreds of iterations
just fine.

I had looked at ‘ptob_close’ and related code but didn’t see this issue;
good catch!

If you plan to push a new release, we’ll just upgrade in Guix; otherwise
we can apply the patch locally.

Thank you!

Ludo’.
