That previous time we were just lucky: the problem disappeared after a
merge from the other branch.  Not sure we even know what was the
problem back then.

Your report is not detailed enough, as you don't show some part of the
script you run, and don't tell where exactly it hangs.  Please provide
those details to allow further investigation.

Thanks.
