[Pharo-dev] Interrupt a locked pharo image from outside

Hi all, anybody knows if it would be possible to generate an external interruption (a signal) from outside the Pharo process which would trigger a Ctrl+. interrupt? OSProcess 4.5.13 has a tendancy to lock the image on some linux systems (ubuntu 14.10 at least), and it would be nice to be able to interrupt it to be able to see where it is blocked. "killall pharo" or Ctrl+C does not give much information :( Thanks, Thierry
