-% Forces a program compiled for generational GC to use two-space copying
-% collection. The two-space collector may outperform the generational
-% collector for programs which have a very low heap residency. It can
-% also be used to generate a statistics file from which a basic heap
-% residency profile can be produced (see Section <ref name="stat2resid -
-% residency info from GC stats" id="stat2resid">).

-% There will still be a small execution overhead imposed by the
-% generational compilation as the test for old generation updates will
-% still be executed (of course none will actually happen). This
-% overhead is typically less than 1\%.
