It isn't clear to me whether this is an overloaded or misconfigured builder or bug in the underlying platform (CC @rorth), or a bug in the runtime itself (such as #52433; CC @golang/runtime).

(It could also potentially be a bug in the time package or its tests, but that seems much less likely to me given how simple the test is.)
