  vmParameterAt: parameterIndex
  	"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)
