[rand.dist.samp.plinear].  This means we've got a fully tested and functional <random>! 489 tests over 48 sections are passing. :-)  The only thing still on my plate in this area is to back-port some of this technology to random_shuffle/shuffle in <algorithm>.  That will involve shuffling header bits around (<random> depepends on <algorithm>), but it won't entail that much development (compared to what has been required for <random>).
