I added COW to the concurrent GC (

more stable with respect to pause times than the version with reading
write watches.
How do I run benchmarks and what are the newest

If I add the actual copy into heap2 (i.e. every fourth page of 512 MB is

The numbers are not great, but I guess the usual memory usage and number
of modified pages will be much lower. I'll see if I can integrate this

Yes, exactly, but I forgot the recipe to convert COFF/OMF import libraries.
Grab coffimplib.exe.

All more sophisticated GCs have write or read barriers. That makes it
much easier to keep track of modifications during concurrent collection.
Right, now I start to remember.
