4469 be associated with a window, buffer, or frame (e.g. window configurations,

4470 glyphs) but should not obviously be included in the usage counts.

4474 particular way of partitioning it into groups. Within a slice, there
|
|

4475 is no overlap between the groups of memory, and each slice collectively

4476 represents all the memory concerned.
