Comment:
This issue is much more important now we have dll's. Imagine a program
that calls out to a Haskell dll, and then returns some result. If the
intermediate computation uses 200Mb of RAM then after returning it's very
easy to have 200Mb of heap with virtually nothing in it. The argument that
other Haskell bit's will soon reuse that heap is also less valid with
dll's, as the main program will not be sharing the same heap.
