* Test case to show that parallel builds of different fixed-output

Browse source 
derivations that produce the same output path don't work properly
  wrt locking.  This happens a lot in the build farm when fetchurl
  derivations downloading the same file on different platforms are
  executed in parallel and then copied back to the main machine.
