The problem here is how to compute the speed of an incremental
collector given those parameters. Suggestions are wellcome.

I'm not sure about that. It seems much easier to ensure worst-case
memory with a mark-and-sweep collector. CPU usage (average) also seems
to increase with an incremental GC, due to higher administrative
overhead.
