Hi Jarkko
Thanks for your review.

With different cgroups, the script starts one or multiple concurrent SGX
selftests (test_sgx), each to run the unclobbered_vdso_oversubscribed
test case, which loads an enclave of EPC size equal to the EPC capacity
available on the platform. The script checks results against the
expectation set
