 > The same should be doable for memory consumption. Not sure how that is
 handled in `rbm` atm but having something like `VM_MEMORY` there as well
 sounds like a good idea.

 As we are using containers and not VMs, the memory is shared between the
 host and the containers. This is also the case in gitian when building
 with LXC, where `VM_MEMORY` is ignored in that case.

 If we want it we should be able to add an option to set the limit of
 memory usage for the container:
 https://github.com/opencontainers/runtime-spec/blob/master/config-
 linux.md#memory
 But given that the memory is shared with the host and there is no memory
 assigned to the container only, I'm not sure it is useful.
