.PARALLELSYNC, as currently coded.

Well ... that's no longer the feature I signed up to contribute, and I
don't have or see a major use case for it. I think the issue most
people have with parallel builds involves debugging
scheduled/automated builds with output to a log file. I can't think of
a situation where the above feature would be important, but if someone
wants to add it as a further enhancement I'm all for it, assuming my
enhancement makes it into the codebase in the first place.
