like, literally the whole personality: you point her at a remote CPU and she expires that CPU's global-base timers. periodt.

yes she returns void. no she does not want to hear about it. 🫶

💜 DESCRIPTION 💜

Expire timers of global base of remote CPU. that's it, that's the tweet. 💀

she reaches over to the global base of the remote CPU and expires its timers. no cap, that's the entire job description — she's not doing your local timers, she's not doing a vibe check on anything else, she's just handling the remote CPU's global base timers and dipping. icon. 👑

fr fr the only claim on the table is: expire timers of global base of remote CPU. don't go inventing extra behaviour for her, she's booked and busy. 🎀
