Do you have any reason to believe that such a change would reduce
memory consumption?


I have reason to believe that it would increase performance on low memory systems/large translation units: it seems that current gcc gc performs a full memory scan on each collection, right? at least if gcc uses more memory than physically available it spends a _very_ long time swapping during collections.
boehm gc could help here since it is a generational collector.
