Is the itkMemoryProbesCollecterBaseTest useful? It fails on macOS, at least in some conditions

The itkMemoryProbesCollecterBaseTest fails on macOS, at least in some conditions, ex:

https://open.cdash.org/tests/1690707341

where it gives:

Freeing memory should result in less memory but it is 262216kB instead of 262164kB

I have a suspicion that this test is quite old, and being tripped up by modern OS memory management (ex: memory compression and other magic).

I wonder if this test really gives any value?

In fact, unless I've missed something in my searching, itkMemoryProbe* is only used in Examples and Tests...

Of course, that class is meant for testing and debugging. Perhaps increase the amount of memory being released? That should prevent it from being lost in the noise.
