> This test is to isolate one single process with one thread in cgroup, and checks the number of processes and threads in the cgroup before/after isolation. The previous test case uses "sh -c "while true; do sleep 1; done;"" as the process, however, it periodically forks a child process "sleep 1" in cgroup causing the test failure (expected number of process/thread should be 1, but here is 2). This patch is to issue a "cat" command, so there will be only one process in cgroup.
