issue46234 is flaky on slow machines, so increase the timeout to 90s. Note that that test timeout already got increased from 30s to 45s in CL 382774, but it was still not enough. Fixes #50973 Fixes #67558 Fixes #74277 Updates #65040 Cq-Include-Trybots: luci.golang.try:gotip-darwin-amd64_14 Change-Id: I809249a05c6ca65fb6c44375c8de5758f21dbb91 Reviewed-on: https://go-review.googlesource.com/c/go/+/747520 Auto-Submit: Quim Muntal <quimmuntal@gmail.com> Reviewed-by: Cherry Mui <cherryyz@google.com> LUCI-TryBot-Result: Go LUCI <golang-scoped@luci-project-accounts.iam.gserviceaccount.com> Reviewed-by: Dmitri Shuralyov <dmitshur@golang.org> Reviewed-by: Dmitri Shuralyov <dmitshur@google.com>
