Public bug reported:
On Ubuntu 12.04.2 in an lxc container, twice now I've caught
debuild -b -uc -us -kfoo@bar > world.log 2>&1
in the act of hanging after printing the line 'Finished running lintian.'.
In both cases, killing the 'tee' process let the process finish.
Here's what I saw this time with ps:

$ tail -n 1 /home/buildbot/src/ob-repobot/world.log
Finished running lintian.
It's a bit of a mystery. I guess I should find out what's got the other
end of the pipe open next time?
Maybe I should add prints to /usr/bin/debuild.pl; there aren't many lines
between where that message
is printed (line 1251) and where the script exits (line 1304).
