Zortech's VCM linker doesn't have this problem.

Check out Zortech's VCM linker. It enables overlays to work much like
virtual memory, i.e. overlays are loaded on demand and placed anywhere
in memory where there happens to be room. Overlays are removed from
memory when malloc starts running out. There's an article explaining
the mechanics of it in the July C User's Journal.

P.S. I wrote it.
