      Add a write barrier for TVAR closures · 6d784c43
      Simon Marlow authored
      This improves GC performance when there are a lot of TVars in the
      heap.  For instance, a TChan with a lot of elements causes a massive
      GC drag without this patch.
      There's more to do - several other STM closure types don't have write
      barriers, so GC performance when there are a lot of threads blocked on
      STM isn't great.  But fixing the problem for TVar is a good start.
