Running emunittest 0.5 suite in sequential stress test mode for a bit more than an hour and looking at the resulting DMD, it gives the following twice-reported blocks:

Twice-reported {
  ~73 blocks in heap block record 1 of 3
  ~2,789,253 bytes (~2,789,253 requested / ~0 slop)
  Individual block sizes: 262,144 x 5; 131,072 x 9; 8,192 x 14; 4,096 x 4; ~4,093 x 41
  0.06% of the heap (0.06% cumulative)
  94.58% of twice-reported (94.58% cumulative)
