Much better on the copy_of calls:
% cumulative self self total
time seconds seconds calls ms/call ms/call name
0.31 67.62 0.29 416 0.70 2.72
$ gem -v
Test suite startup is no faster, but now I can no longer be sure
rubygems is the problem.
(Something in Rails gives widely varying test run times, sometimes 6s,
sometimes as much as 9s.)
