@aclements points out we might just be running this test under conditions we previously weren't, because they moved this test out of it's original location. It's also possible we were having this failure before under misc/cgo/test, but there don't seem to be any other failures there.

[mknyszek]

Added release-blocker until we can figure out more details. Probably won't be long-term.

This test has been in the tree for years, but never ran before CL 493603, which I submitted 2 days ago.
