CPU utilization when idle

[cherio]

Hello everyone, I am finding myself using vim less and less in favor of fresh.

One thing that I keep noticing is app CPU consumption, which makes me wonder whether there is a never-sleeping loop of some sort. It is small, but for a terminal-based application written in Rust, I expect to see zero CPU when it is sitting idle (and even in a minimized terminal window). htop reports CPU bobbing up and down between 0% and 2%, but mostly above zero. Disabling animations, increasing File Tree Poll interval and running with --no-plugins has no effect.

This is certainly not much and could be ignored by heavy desktop users, though in the context of terminal+rust, it makes me wonder about the possible design issue.
