 As of r14054:

 {{{
 $ bin/allknn -k 10 -r covertype.csv -d d.csv -n n.csv
 $ bin/allknn -k 10 -r covertype.csv -d dn.csv -n nn.csv -N
 $ diff d.csv dn.csv | wc -l
 640
 }}}

 But in r13957:

 {{{
 $ bin/allknn -k 10 -r covertype.csv -d d.csv -n n.csv
 $ bin/allknn -k 10 -r covertype.csv -d dn.csv -n nn.csv
 $ diff d.csv dn.csv | wc -l
 0
 }}}

 So some change (probably r13958) caused the kd-tree traverser results for
 allknn to be invalid; yet, it does not fail the test.
