Miguel, I don't want to drive you crazy but examining and debugging the
libgc code we've found that the pages are kept marked as "used" instead
of free (David can give you more info in case I'm missing anything).
That's why I don't think fragmentation is the problem. If marking were
ok, the entire mem would be freed (as it happens with 64bits mono).
