SubjectRe: [PATCH 0/2] pipe: Fixes [ver #2]
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.
