Doubt on zdb -b output (leaks?)

The pool of my Solaris 11.1 station is as follows:

# zpool status
  pool: rpool
state: ONLINE
  scan: scrub repaired 0 in 1h3m with 0 errors on Thu Mar  6 09:28:17 2014
config:

    NAME          STATE     READ WRITE CKSUM
    rpool         ONLINE       0     0     0
      mirror-0    ONLINE       0     0     0
        c3t0d0s0  ONLINE       0     0     0
        c3t3d0s0  ONLINE       0     0     0

errors: No known data errors

Not long ago I did a scrub which resulted in no errors as well.

But reading another post, I tried to run a "zdb -b" which took long time and resulted in:

block traversal size 107356391936 != alloc 107358380032 (leaked 1988096)

    bp count:         1524983
    bp logical:    110762148864      avg:  72631
    bp physical:   107880348672      avg:  70742     compression:   1.03
    bp allocated:  108280984064      avg:  71004     compression:   1.02

Howdy, Stranger!
