*** TODO repro locally

on my 1st run of out/Release/unit_tests (no filter) under release DR, it
does indeed sit here:
[ RUN ] CpuInfoProviderTest.DoOnlyOneProcessorCpuSampling

running CpuInfoProviderTest.* in isolation natively or under DR: runs fine,
and quickly.

nothing obviously wrong: sitting in gtk+ main event loop (g_main_context_iteration)
