It would appear "process group" isn't the right thing to look for. I am
looking into it now ...
ps -eo "%U%p%P%g%c"
seems to indicate that all of my processes have the same process group. Even
all my colleagues have the same process group. So if I were to "killall -g" I
would be attempting to kill everything of mine, and all my colleagues too ...
Not just an isolated process tree.

Subject: Re: [lopsa-tech] kill process tree
You should be able to do this (at least on linux) with killall -g,
specifying the process group id of set of processes that you want to
kill. Note that this is less than rigorous; child processes can leave
their initial process group. (This is one of my pet peeves about the
unix process management API; it is possible for child processes to
escape control of their parent through a combination of forking and
setsession'ing.)
