Description

The netbsd-amd64-8branch (NetBSD 8.0+) builder is back and NetBSD is kinda working for the first time in ages.

But only kinda.

The runtime tests fail with a timeout about two thirds of the time.

Examples:

https://build.golang.org/log/9ff11d9a995eb3b2555ce8f88bb3280c91639386 https://build.golang.org/log/d9a762c61874b62e34cec30f79ddc21a190922f7 https://build.golang.org/log/7ab9f1d000be47604a25b1ebf17fc55f5799d0ec https://build.golang.org/log/6678e6c8dfb7533054836eb140f9eff8416e3a30

Many more at https://build.golang.org.

It'd be nice to have NetBSD happy for Go 1.10, considering the Go 1.9 news that NetBSD support was dead (https://golang.org/doc/go1.9#known_issues) which prompted a number of people to help fix things up.
