About 26-28 hours ago in #debian-release on IRC:

<nthykier> damn, a britney run in 5 minutes
<adsb> they happen
<adsb> you've been spoilt by never seeing b1 at her "finest" *cough*
<aba> you mean, running for more than a day?
<Ganneff> adsb wants night-long runs?
<aba> I can remember runs where we had to block certain packages to
      make sure the run could actually end *sometimes*
<adsb> I'm quite happy with just the memory of that sort of run,
       thanks :P
<nthykier> I don't mind being spoiled if it stays at 5 minutes :P

I took the liberty of collecting the resulting data for the Britney test suite. In its reduced state[1] in runs in 30 seconds on my machine.  It is already my favourite live data sample in the test suite.  :D

[1] Only i386 and amd64 are considered, manual hints are ignored etc.
