--- Comment #21 from boger at us dot ibm.com --- I'm confused by the description of -a in the go1.4 documentation. I asked about this before and the answer was that each invocation of 'go build' would create a copy of the built package which was then used for the current build but then thrown away. But that must not be the way it works?
