Unrelated side note: there may be some missing dependencies in the
build infrastructure or something, because when I tried Jeff's script
that did that "test the merge and the two parents", and used the
pack-file of the kernel for testing, I got:

never mind the performace, notice the *coll* in that last case.
But doing a "git clean -dqfx; make -j8" and re-testing the same tree,
the issue is gone.
I suspect some dependency on a header file is broken, causing some
object file to not be properly re-built, which in turn then
incorrectly causes the 'ctx2.found_collision' test to test the wrong
bit or something.
