"nice" seems to be doing quite nicely :-)To me this capping functionality is a similar functionality to that provided by "nice" and all that's needed to make it useful is a command (similar to "nice") that runs tasks with caps applied. To that end I've written a small script (attached) that does this. As this is something that a user might like to combine with "nice" the command has an option for setting "nice" as well as caps.
Usage:
withcap [options] command [arguments ...]
withcap -h
Options:
[-c <CPU rate soft cap>]
[-C <CPU rate hard cap>]
[-n <nice value>]
-c Set CPU usage rate soft cap
-C Set CPU usage rate hard cap
-n Set nice value
-h Display this help
