Issue #115
Go accepts runtime/mainthread package for main-thread work
The Go team has accepted the long-running proposal for a new runtime/mainthread package, giving GUI and other platform code a sanctioned way to pin work to the main OS thread instead of hand-rolling it on top of LockOSThread. On the practical side, a writeup on container GC pacing revisits what GOMEMLIMIT actually fixes when Go processes burn 60% CPU inside memory-capped pods, which is still the GC story most teams run into before they ever need mainthread.
