  "parameterIndex is a positive integer corresponding to one of the VM's internal
  parameter/metric registers.  Answer with the current value of that register.
  Fail if parameterIndex has no corresponding register.
  VM parameters are numbered as follows:

  2 end of young-space (read-only)
  3 end of memory (read-only)
