With bigger values, there is a chance that the background process terminated and, as the system PIDs cycle, there is another process with the old PID. And you don't want to kill that
If you have a shell with job control, you can use the safer kill %1.

Unix standard shells do not have job control.
I am just thinking about another background process:
Code:
# fire the background command, cut standard connections to this shell some_command some_arg1 some_arg2 </dev/null >/dev/null 2>&1 & task_pid=$! # fire a watchdog, again cut the connections (sleep 900; kill $task_pid) </dev/null >/dev/null 2>&1 & watchdog_pid=$! wait $task_pid kill $watchdog_pid
