      Description

        The spec for the heap sampling system has three elements that should be fixed/updated:

        1) Instead of sampling_rate, it should be referred to as a sampling_interval; since a rate is a frequency.

        2) The spec does not define correctly how soon does it produce a callback when setting the interval to 0; this can lead to confusion.
              Fix this by putting in the spec that the setting of a rate is not an immediate effect, it may take time to start

        3) The sampling interval should be defined more generally, instead of providing information such as geometrical variable.
