Thanks Lawrence, the following line looks suspicious to me:

    reaped #<Process::Status: pid=4382,exited(0)> exec()-ed

Which makes it seem like
http://git.bogomips.org/cgit/unicorn.git/commit/?id=3f0f9d6 didn't get
applied (and I just checked the 1.1.2 gem and it looks good to me)

Can you dump out the ENV hash in your before_exec hook of your
unicorn.conf.rb?  I'm wondering if GEM_HOME or GEM_PATH is set
and doing anything funky, causing you to load an old version
of Unicorn:

  before_exec do |server|
    ENV.each do |key,value|
      server.logger.info "#{key}=#{value}"
    end
  end

It does, I create a similar line in the unicorn_setup() function of
test-lib.sh
