[loudness~] memory leak : RAM use constantly increases over time (Windows)

Summary:
The [loudness~] object increases the RAM used over time on Windows.

Steps to Reproduce:
Setup a [loudness~ @interval 50] object and run an audio file through it. For more more obvious results, copy 10 versions of the loudness object and have it report into the [live.numbox] with the LUFS units like shown in the maxhelp patch.

Expected Results:
Over time, there should not be unlimited increasing RAM use.

Actual Results:
Over time, the memory used by Max on Windows increases until audio processing starts to get garbled/glitchy.

Regression:
Max 9 (new object).

Notes:
Depending on the requirement, [average~] in RMS mode, or maybe [M4L.envfol~] for envelope following for workarounds.
