Description

Ducc's agent currently assigns only memory control for a process launched into a CGroup container to enforce fair share use of memory. Extend this by adding a cpu control to make sure a single process (and its children) doesn't take more cpu than its fair share. Cgroups will allow a single process to use 100% of its CPU, but when another is started the cpu control group will reduce the allotment to 50%.
