Thanks, Julien! Looking forward for your results. Meanwhile, the code has
been running for a week on a single Netflix box. And for 24 hours on a
set of boxes as A/B test against non-patched code. Since our connection
rate is low, and we never seen accept_mtx to be a major problem in our
profiling, the A/B test didn't show any statistically significant
improvements. But my biased eye of course sees some improvements in the
Totus tuus, Glebius.
