It allows to register multiple memory thresholds and gets notifications
when it crosses.

To register a threshold application need:
- create an eventfd;
- open file memory.usage_in_bytes of a cgroup
- write string "<event_fd> <memory.usage_in_bytes> <threshold>" to
  cgroup.event_control.

Application will be notified through eventfd when memory usage crosses
threshold in any direction.
