   1 // This test does enough allocation and deallocation that the time-unit,
   2 // when measured in bytes -- 6,000,000,000 -- exceeds 32-bits.  It also does
   3 // it in a slightly uneven fashion so we get a range of different totals
   4 // for the snapshots, including a zero-sized detailed snapshot.
