Note that netbsd-amd64-9_0-n2 is one of the builders not believed to be affected by #49209.

As with #50138, a good starting point is probably to modify the test to terminate the process with SIGQUIT in case of a hang.

From https://build.golang.org/log/52da2ef801b2cf199641dab714931fe2cc1727ea, it appears that this test normally completes in under a second.
