Comment 10 for bug 299847

Testing on rimu with lamont's help, it seems to be an alignment issue. Setting /proc/cpu/alignment to 2 (fixup) causes the following failures:

# Failed test 'num_segments'
# at t/sharelite.t line 40.
# got: '1'
# expected: '3'

Meanwhile, setting it to 3 (fixup+warn) causes one build failure to go away, and the following make test results:
