Factor/To do/GC
- id-hashcode
- promote objects to tenured after a certain number of collections (or in some other way improve generational strategy because aging space thrashes)
- mark/sweep for oldest generation--what kind of compaction should be used?
- - plain old mark-compact
- - the compressor
- - mark-copy
- - Immix
- incremental gc
- Distant future: parallel GC, concurrent GC
- Card marking for parts of arrays
- card marking for code heap to speed up
collect_literals
If we go with immix, here's the plan:
- Implement mark-sweep(-compact), which will be used for the large object space (necessary since immix can't handle large objects)
- Implement a mark-region collector without evacuation or lines for small objects
- Implement evacuation
- Implement lines
