o Minor bugfixes (relay):
- Do not try to parallelize workers more than 16x without the
user explicitly configuring us to do so, even if we do detect more than
16 CPU cores. Fixes bug 19968; bugfix on
0.2.3.1-alpha.
o Minor bugfixes (testing):
- Avoid a unit test failure on systems with over 16 detectable
CPU cores. Fixes bug 19968; bugfix on
0.2.3.1-alpha.
