    Description

      Need to have a function which returns the max heap size (ie what is set by -Xmx). This might be in class Runtime and look like:

      public long maxMemory();

      We alse need a function returning the number of processors on the underlying hardware. This could again be in class Runtime and look like:

      public int processorCount();
