+  blocking sockets to read and write from the tty so that the "crun
+  exec" process doesn't hang when the terminal is not consuming any
+  data.
+- linux: remove the workaround needed to mount a cgroup on top of
+  another cgroup mount.  The workaround had the disadvantage to

+  currently used is to mount a temporary tmpfs between the two cgroup
+  mounts.
