  Each container is placed in its own cgroup. Cgroups make each container use a 
  fair share of CPU relatively to the other containers. This prevents
  oversubscription on the runner where one or more containers hog the CPU and
  leave no computing resources to the others.
  
  The way cgroups allocates CPU time is based on shares. CPU shares do not work
  as direct percentages of total CPU usage. Instead, usage share is relative in
  a given time window to the shares held by the other containers. The total
  amount of CPU that can be overall divided among the cgroups is what is left
  by other processes that may run in the runner.
  
  Generally, cgroups offers two possibilities for limiting the CPU usage:
  <em>CPU affinity</em> and <em>CPU bandwidth</em>, the latter of which is used
  
negative.code: 
  * CPU affinity: It consists of binding a cgroup to certain CPU cores. The actual amount of CPU cycles that can be consumed by the cgroup is thus limited to what is available on the bound CPU cores.
  
  * CPU bandwidth: Sets the weight of a cgroup with the process scheduler. The process scheduler divides the available CPU cycles among cgroups depending on the shares held by each cgroup, relative to the shares held by the others.  
  For example, consider two cgroups, one holding two shares and one holding four. Assuming the process scheduler gets to administer 60 CPU cycles, the first cgroup with two shares will get one third of those available CPU cycles, as it holds one third of the overall shares. Similarly, the second cgroup will get 40 cycles, as it holds two thirds of the collective shares.
  
  The calculation of the CPU usage based on the percentage of the total CPU power
  available is quite sophisticated and is performed regularly as the CPU demands
