I'm on Ubuntu 20.10 and security updates are no longer being provided.

This is not a bug.
It turns out the behaviour I was seeing was due to the fact that swap
accounting is disabled by default and so the perl process was swapping
rather than being killed when its RAM limit was reached.
If I turn swap off (swapoff -a), the process is killed correctly.

Note that the above instructions assuming swapping is off, otherwise
memory.memsw.limit_in_bytes would also need to be set to 100.
The above testing was done on a 3.11.0-17-generic kernel. Re-testing on
an upstream kernel, 3.14.0-031400-generic ("3.14-trusty"), showed the
same problem - the pr
Public bug reported:
This problem reproduces on Ubuntu 13.10 with a 3.11 kernel but, for
comparison, works ok on RHEL 7 with a 3.10 kernel.
Steps to reproduce:
1. Make a directory, for example /home/glyn/cgh1.
2. Switch to root user.
3. Attach the memory resource controller subsystem to a cgroup
