Hi Vladimir,

The code is only executed if CICompilerCountPerCPU (which is disabled by default) is true. So either
CICompilerCountPerCPU was enabled by ergonomics (which only happens if CICompilerCount is default,
see TieredThresholdPolicy::initialize()) or the user explicitly enabled CICompilerCountPerCPU in
which case it should be fine to limit the maximum CICompilerCount that is set, right?

Thanks,
Tobias
