Awesome stuff! Does Go have profile-guided optimization? I'm wondering whether a profile could hint to the compiler how large to make the pre-reserved stack space.

Yep. `go build -pgo=foo.pprof`

		I never noticed much difference with using pgo even after taking a very long real life profile. All the machinery required to get it and put it to CI was never worth the speed-up. Of course YMMV.
