Peak Memory Usage

Can anyone help me understand what Peak Memory Usage is in Arnold or point me to the source of knowledge?

I'm rendering a scene that seems to consume about 180GB of memory, I've actually sat there and watched the total memory + swap on my system monitor to confirm, yet, the job reports about 537GB of "Peak Memory Usage" in the logs.  What does this mean?

Peak Memory is usually higher because of some temporary memory allocations. 

The rest of the memory stats are non-temporary memory usage.

 

Temporary memory could be something like resizing some data structure. For a moment there would be two copies, the old and the new, until after the existing data was copied over, and the old copy deleted.
