Is this shared machine/VM?  What kernel config/version?

Kernel config may be in /proc/config.* , otherwise distros may put
kernel config in /boot/config*

I'm mainly interested in *_HZ and preempt options.

Yikes, wild timings :<

I think the test case is too fragile.  We should increase delta+sleep or
remove test.  Based on comments on thread_pthread.c, 0.1s might be a
lower bound on portable timing granularity.

I think this can fail on your system even with the lib/benchmark.rb
optimization in r47260 reverted.
