os: TestClosedPipeRaceWrite broken on solaris / SmartOS

[bradfitz]

Just noticed that the solaris-amd64-smartosbuildlet builder is all red. It's probably been red for a long time.

I suspect there are just spinning processes in the background.

That builder isn't created & destroyed per build (in either a container or VM). It's just a process running in a loop.

Ah, thanks. Closing this as duplicate of #27566.
