The handoff algorithm is really only good for two cores.
Beyond that we will need to so something more sophisticated,
like have each core hand off to the next one, around a circle.
Even so, the code is a good checkpoint; for now we'll limit the
number of gc procs to at most 2.

This aligns the naming scheme with the testing package and
also lets govet work on more logging calls.

apparently some versions of GNU make cannot
handle the %: %.$O rule. i don't understand why
and don't care enough to find out.
