@bsiegert, @coypoop: could you investigate? This is the only builder exhibiting this failure, and it occurs quite frequently.

(Note that this failure mode appears to predate #49209.)

This is a release-blocker (via #11811) until the test is skipped. (Then it can go in the backlog, because netbsd/arm64 is not a first-class port.)

This test appears to deadlock frequently on the only netbsd-arm64
builder we have (netbsd-arm64-bsiegert). Skip the test to provide
more useful test coverage for other failures.

For #49382
