  Which documentation?

Mailman/Defaults.py.in:677
# BAW: Although not enforced, the # of slices must be a power of 2

$ /usr/share/mailman/bin/qrunner --help
...
    -r runner[:slice:range]
    --runner=runner[:slice:range]
        Run the named qrunner, which must be one of the strings returned by
        the -l option.  Optional slice:range if given, is used to assign
        multiple qrunner processes to a queue.  range is the total number of
        qrunners for this queue while slice is the number of this qrunner from
        [0..range).

        If using the slice:range form, you better make sure that each qrunner
        for the queue is given the same range value.  If slice:runner is not
        given, then 1:1 is used.

        Multiple -r options may be given, in which case each qrunner will run
        once in round-robin fashion.  The special runner `All' is shorthand
        for a qrunner for each listed by the -l option.
...

  If power of 2 is important, it should be noted in qrunner's help too.
  (Also "then 1:1 is used" is wrong, usually 0:1 is used.)

  Sure, I just took last one which was mentioned in strace log.
