Cirno will help you to run tasks and keep your system away from freezing.
See ciron --help for details.
This cirno will send signal to control child process.
SIGALRM is used to notify child when the child timeout.
SIGTERM is used to terminate child when resources are insufficient.
SIGKILL is used to kill child when child refused to self stop.
When Cirno finds that the system load exceeds the set value,
it will use the signal SIGTERM to temporarily terminate the task process in preparation for the next scheduling.
When Cirno detects that a task has timed out,
it will use the signal SIGALRM to notify the process and wait for process to exit on its own.
When Cirno must terminate a process,
it will help the process escape from child process hell (sending the signal SIGINT to its child processes),
and check the child process status in the next scheduling loop.
If these do not work, then SIGKILL will be sent to all.
Run with task list without task name.
