> The {{PubSubDUnitTest}} currently fails when run under stress
> ({{StressNewTest}} job in CI). There are various factors at play here:
> - Test hosts have 96 vCPUs and netty will use 2x this number for each
> EventLoopGroup (of which we have 2). For some tests we end up needing almost
> 1600 threads which seems excessive.
> - VMs are not recycled between every test run but thread resources are also
> not cleaned up synchronously between runs; this seems to be the biggest
> problem.
