If I start mpirun from the command line and type CTRL-C
in the console, all jobs are killed. So I thought, simulating
CTRL-C by sending SIGINT to mpirund would work, but it does
not. Is there any difference between foreground and background
processes? How can I make my program a foreground process when
I execv it? Perhaps that will help..

How did you start your mpirun? (execv?)
