Someone must examine and confirm this is a valid issue and not a duplicate of an existing one.
Milestone
Starting with @aclements CL 23391 ("runtime: pass gcWork to scanstack") yesterday, the runtime tests are consistently timing out on the linux-amd64-noopt builder. See e.g. https://build.golang.org/log/c70503b10af6b554372e2e11f257f7a0d8524678
It looks like these tests are running in anywhere from 10s to 100s on the other builders.
Austin, can you take a look at the traceback and see if this is an important regression for Go 1.7?
