The following test failure for `TestZoneReload` can be observed periodically: `file_reload_test.go:58: Expected two RR in answer section got 2` This failure can be consistently reproduced using the following command (on my machine, at least): `( cd test ; go test -v -race -run "TestZoneReload" ./... -count=500)` test/file_reload_test.go: Address a typo in a test failure message. Sleep for double the file reload interval to avoid a rare race condition between test code and the file plugin's reload code, which is presumably a result of the time it takes to actually reload.
