    List the tree of threads and thread groups that are active in the JVM.

  MONITOR/MEMORY [REQUIRES JAVA 5] (Since NeXtMidas 2.1.0)

      NONH - Amount of NonHeap memory used for methods loaded into memory.

      CURR - Number of threads currently active.
      PEAK - The peak number of active threads.
      TOTL - Total number of threads created.

       nM> system TOP

  2. Show all the threads and thread groups running in the JVM.

  3. Monitor memory and thread info.
