I should mention perhaps that I see such a hanging PTY about once a year, though I can't tell what exactly triggers it. If the GDB testsuite case is reproducible, that's very helpful of course :-) (As it only happens about once a year, and killing the offending term process fixes the issue, I haven't bothered investigating it thus far...) -antrik-
