Hmm. I think I just saw this same bug with a plain kernel compile.
My "make -j32" suddenly came to a crawl, and seems to be entirely single-threaded.
And that's almost certainly because the way 'make' handles load distribution is with a network of pipes that has a token passed to the sub-makes.
So there's most definitely something wrong with the new pipe rework. Well, I can't _guarantee_ the pipes are the cause of this, but it does smell like it.
