<pre>This test is sometimes failing on Linux. When it fails, it's really timing
out, and still running.
Attaching to it, here's the call stack. It's busy waiting on whatever it's
doing, because it's still accumulating run time at this point (7 minutes in
when I attached to it).
Attaching to program: /mnt/ssd/work/macosx.sync/mbp-svn/build-debug/bin/lldb,
