套件：loadwatch（1.0+1.1alpha1-8） [debports]
Run a program using only idle cycles
loadwatch forks a child process and only allows it to run when the system load meets user-defined parameters. It allows you to specify that a program should run only if the load is below a specified point, and will stop it when that point is reached. When the load falls below a second specified point, the program will be continued. The user can also specify the system load sampling period.
