Subject: Re: master: t5800-remote-helpers.sh hangs on test "pulling from remote remote"

Hi Sverre,
The 'pushing to local repo' test of t5800 which pushes using
git-remote-testgit.py results in a deadlock for Stefano. Invoking
fast-export/fast-import manually seems to work, however. I don't know
what else to try at this point.
I am pasting some relevant results below.

This is Stefano's output, at which point git fast-import hangs. On my
box, fast-export runs a little later (after Got command 'export' with
args ''), but I don't see how that would matter.
Below is the result from running fast-import/fast-export manually:
