Killing every process on the system that happens to have the same name as the one we've started is error prone and dangerous. We might kill processes we haven't started and other processes might rename themselves at runtime so that we don't find them anymore. The process ID is obtained by outputting it as very first thing on stdout and then starting the process with "exec", so that it isn't forked.
