Public bug reported:
box.truncate() hangs forever with 100% CPU usage when primary key is not
at field 0.
Example:
slab_alloc_arena = 0.1
pid_file = "box.pid"
primary_port = 33013
secondary_port = 33014
admin_port = 33015
space[0].enabled = 1
#namespace[0].expire_field = 2
space[0].index[0].type = "TREE"
space[0].index[0].unique = 1
space[0].index[0].key_field[0].type = "NUM"
space[0].index[0].key_field[0].fieldno = 1
kostja@atlas:~$ cat foo.log

insert into t0 values (1, -2)
insert into t0 values (1, 3)
