  - Fix system-dependent code in src/gc/system.c (See #273)
 
- - Implement write barriers. They're needed to maintain the remembered set for generational GC and to update the mark stack for incremental GC. There is a proposal in PDD09 but using macros doesn't work well with pluggable GC cores and using function calls is expensive. Two approaches for efficient write barriers are card marking and sequential store buffers. Card marking is preferred for procedural languages that might make a lot of assignments.
