Total memory footprint: 1469.1MB
On Windows, dennard returns the size of the "working set".
The working set consists of the pages of memory that were recently referenced
by the process.
On macOS and Linux, dennard`` gathers the sum of dirty/anonymous allocations in one or more processes along with their attributable kernel resources (KPRVT). Shared allocations only contribute to the footprint once, regardless of the number of times that they are mapped into any number of processes. The goal is for the resulting number to be as close as possible to what the macOS Activity Monitorreports asMemory` usage.
