Incidentally, the reason I didn't jump into this thread until the
patches showed up is that I don't think it actually matters what the
parameters are named.  They're going to require documentation
regardless, parallism just isn't something people grok instinctively.

I care about how the parameters *work*, and whether that's consistent
across our various resource management settings.
