When our continuous integration machine starts with a stock 5.10.0 and tries to upgrade M::B, CPAN.pm sees a build requirement on 0.33_01 and suspends the build to follow the dependency, which leads to a new build with a build requirement on 0.33_01...
Thankfully, we've got a timeout on that build. So, kindly don't put M::B into the build requirements if building M::B itself.
