But a good logging system would still tell us what was being
built.  If two threads were trying to build the same file, then we
know we need to add a lockfile or something like that.  If only
one thread was building that file and it still dies, then we know
it's just that input.

Now that I think aboud it, the parallel build thing seems very
plausible to me.  Multiple languages can be building exactly the
same snippet at the same time, and I could well imagine that this
will cause boom.

... but without a logging system, we might as well be theorizing
about the universe before the big bang.  Potentially fun, but not
likely to be useful for any practical purpose.
