What's Wrong?
Every time my statusline executes, it spawns a shell call to sysctl -n hw.physicalcpu_max. This shell call triggers logging by my company's security software, creating unnecessary overhead.
What Should Happen?
I'm not sure why the statusline cares about how many CPU cores I have. But if it does, I'd suggest making the sysctl call once and caching the result. The number of CPU cores isn't going to change.
