--- Comment #2 from Frank Ch. Eigler <fche at redhat dot com> ---
It doesn't make sense. I wonder if the gdb case tickles some kernel problems,
or maybe violates expectations of the golang runtime -- maybe only pausing a
few threads rather them all? I wonder if a perf-probe set attached to the same
probe points can demonstrate the problem (vs. systemtap). See
scripts/stap2perf and/or stap -DALIBI.
