This looks like the same failure mode reported on solaris-amd64-oraclerel in #35159. (Keeping this issue instead because it already has a watchflakes pattern configured.)

Since there are no common elements between netbsd/arm64 and solaris/amd64, this looks to me like a platform-independent net/http bug (attn @neild).
