+* Hooray: look into adapting the existing GC scheme to support multiple generations - which is a straightforward optimizations even without being a GC expert, it basically boils down to having a single typedef enum {GC_GEN0, GC_GEN1} GENERATION; in code.h and then changing all places in $SG_NASAL to use the GC_GEN0 pool by default, i.e. instead of having &globals->pools[type]; - we would have &globals->pools[GC_GEN0][type]; for starters - the GC manager would then by default only mark/reap the GEN0 (nursery, young generation), promote any objects that survived the GC phase to GEN1, and only ever mark/reap GEN1 if GEN0 has to be resized. {{Not done}}
+* marking/reaping could be parallelized using several threads, for each pool - by using write barriers to sync access to naRefs
