runtime: implement experiment to replace heap bitmap with alloc headers #golang
TLDR: This change replaces the 1-bit-per-word heap bitmap. The purpose of this change is performance. There's a flat 1.5% memory use reduction.
https://go-review.googlesource.com/c/go/+/437955
Also, where is a ticket?? 😢
