Not sure that this is really all that useful. At least I don't have the
patience to examine all this, and I'm not sure it contains the needed
info in the first place. If you were to ensure your build is using
-fno-omit-frame-pointer in cflags and then used "perf record -a -g"
while the test runs and "perf report -g" once it's finished, you'd get a
useful profile that would show who is acquiring the problematic lock and
why.
