+ * A secondary goal is to be able to categorize memory used by a process into

+ * accounting for stride, bit depth, rounding up to page size, etc.

+     * combination of pid and memory type. For each memory type that it
+     * recognizes, the HAL must fill out an array of memtrack_record
+     * structures breaking down the statistics of that memory type as much as
+     * possible. For example,
