I have tested the public patches from ad@ (slightly older), pooka@
(applied) and myself. Neither of that seems to fix all the performance
issues and all the dead lock conditions, but the all of them improve the
situation and at least the combination of pooka's changes with ad's
recent patch seem to make the timing range small enough that it can't be
hit during the parallel bulk builds.
