    But you don't need something as complex as CKRM either. This capping
    functionality coupled with (the lamented) PAGG patches (should have been
    called TAGG for "task aggregation" instead of PAGG for "process
    aggregation") would allow you to implement a kernel module that could
    apply caps to arbitrary groups of tasks.
