I must admit that I don't know how to find the right limit. I
especially don't know how to do it automatically, which is why there's
no default limit in DrScheme.

A paranoid GC may be to blame for this kind of problem. The collector
wants to make sure that it has plenty of memory available to perform a
collection, and it conservatively estimates that it will need as much
memory as currently allocated to perform a collection; it gives up in
cases when it shouldn't. This initial factor of 2 is overkill by a lot,
and we can tune it.
