Why not keep the 3 states, but just treat unmarked blocks as free?
Then the next time you go through tracing, change the bit to free if
it was already marked.
Sorry, if it was already *unmarked* (or marked as garbage).
Yah, understood. Unfortunately I just realized that would require either
to keep the bits together or to scan two memory areas when trying to
allocate, both of which have disadvantages. Well, I guess I'll go with
the post-tracing pass. -- Andrei
What is the problem with keeping the bits together?
