So, let's think what we can do at runtime. Suppose RTS takes the parameter -- upper limit of consumed memory. When it sees that memory consumption is close to upper bound, it can:

1. force garbage collection

This is already implemented. See the -M RTS option.

Correct me if I'm wrong - it's been a while since I tried to use the -M option to deal with Gitit memory usage on darcs.net - but doesn't -M just kill the program after it reaches a set RAM, and doesn't trigger any GCs? -- gwern
