  Log:
    vm_trace: remove rb_postponed_job_t->flags
    
    This field has been taking up space for 5 years and never used.
    Save 8kb of memory on x86-64 for now.  If we ever care about
    this flag, we'll simply re-add it.
    
    * vm_trace.c (rb_postponed_job_struct): remove flags
      (postponed_job_register): comment out flags assignment
      [ruby-core:87052] [Misc #14764]
