What is the effect of restricting a child process to a subset of the parent's resources?

Restricting a child process to a subset of the parent's resources is an effective strategy for managing system resources and overall performance. By limiting the amount of resources that a child process can utilize, the operating system can prevent a scenario where a single process monopolizes system resources, leading to performance degradation or even system crashes.

When a child process is confined to fewer resources, it ensures that other processes in the system, including sibling processes, have enough resources to function effectively. This restriction helps maintain a balance in resource allocation, thereby enhancing overall system stability and preventing overload situations. If all child processes were allowed to utilize unlimited resources, it could result in resource contention, ultimately degrading performance across the board. Therefore, this approach directly addresses the potential for resource starvation and allows for a more equitable distribution of resources among processes.
