I hope I does :)
But I have to point out, that a randomly distributed *and*
sparse set is the worst case scenario for the 'large_bitset'
(1) If you have long runs of bits set to '1' (or repeating bit patterns),
interval compression kicks in.
(2) If you have regions with randomly but relatively densely distributed
bits, bit compression will help.
For a randomly distributed and sparse set non of these
compression techniques can be applied. In the worst case
you are holding one tree node of the underlying rb-tree for
