    Subjecta nohup-like interface to cpu affinity
    Robert and Ingo,
    A nohup-like interface to the cpu affinity service would be useful. It
    could work like the
    following example:

    $ cpuselect -c 1,3-5 gcc -c module.c

    which would restrict this instantiation of gcc and all of its children to
    cpus 1,3,4, and 5. This
    tool can be implemented in a few lines of C, with either /proc or syscall
    as the underlying

    On another subject -- capabilities -- any process should be able to reduce
    the number of
    cpus in its own cpu affinity mask without any special permission. To add
    cpus to a
    reduced mask, or to change the cpu affinity mask of other processes, should
    the appropriate capability, be it CAP_SYS_NICE, CAP_SYS_ADMIN, or whatever
    is decided.
