This was useful; thanks for the suggestion. My current emacs session has
been running for 4 days. The OS ways that it's usinng 1143MB of RAM.
This is too much, and will keep growing quickly with time.

No significant difference is observed when I (garbage-collect). It looks
like the bulk of the memory is in the "heap". Is this meaningful to
anybody? Any insight greatly appreciated.
