Linux's control groups are a resource management system, an attempt to do resource management better than the POSIX rlimit mechanism. They are not job objects, and do not do all of the things that jobs do (on operating systems that have them). However, a job object is the kind of mechanism that people want for this sort of thing. * http://jdebp.eu./FGA/linux-control-groups-are-not-jobs.html http://jdebp.eu./FGA/linux-control-groups-are-not-jobs.html
