JFTR: That happened with the "pbuilder", which untars a minimal
system, chroots into it, installs required build-dependencies, builds
the package and cleans up. It keeps a terminal. As mentioned it
happened once, and just "Ctrl-C, Cursor-up, Enter" succeeded.

This was with sbuild, which does similar things, but as AFAIK a daemon
and without connected terminal. As you can see on
this seems now reproducible on that architecture with that build
system. At least I currently consider it reproducible there. Will
investigate later today, likely in the evening.

They didn't happen in the past (at least I can't remember any cases --
not counting any issues on Hurd, though) and I don't think the build
systems have changed that much recently.

Nevertheless, that guess still sounds very reasonable for me. So
thanks for that background information, it will help me to investigate
the issue.
