The concurrent set, managed id-table dups and symbol id-entry buckets are reachable from every Ractor via VM-global state (the frozen-string/symbol tables, shape-tree edge tables, the symbol table), so flag them shareable -- as enc_list_update already does for the encoding list.

concurrent_set.c now includes ruby/ractor.h for RB_OBJ_SET_SHAREABLE. (id_table.c is #included into symbol.c, which already depends on ruby/ractor.h, so no separate entry is needed.) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
rb_postponed_job_preregister already stores table[i].func/data with atomic CAS/EXCHANGE, but rb_postponed_job_flush read them non-atomically, which races when a job is (pre)registered on another thread while a job fires. Load them atomically. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
