The param MEMORY_HIGH_WATERMARK is disabled on Linux with the comment:
// The non-windows memory manager does not have access to memory sizes.

After inspecting src/util/memory_manager.cpp, I believe this comment may no longer apply.

Is there still a reason not to enable this feature for non-Windows builds?

Thanks for reporting this issue. It affects the master (official release) branch, but it is not an issue in the unstable (work-in-progress) branch.
