Please read my previous message: "I don't think it is acceptable for
CRuby (because CRuby moves memory areas!)".

Concurrent tracing needs an assumption that "do not move (free) memory
area except sweeping timing". Current CRuby does.
For example: "ary << obj". Yes, the CRuby's memory management strategy
(assumption) is different from normal interpreters.
