We should mention that this function should be called after memory is
properly initialized,
i.e. at least keep statement "Should be called after ..."

What about saying something like "Compact old objects and grow oldspace to
SPACESIZE bytes,
if it's not there already.  Should be called after the sweep has occurred."

I removed these statements because it seems that they are does not match
with current
implementation of _gst_grow_memory_to ().  However, I did not find all the
change history
of that function, so maybe I have removed too much.
