Say why the watchdog exits the ordinary way

Browse Source 
It calls exit and not _exit, and the reason is the opposite of what the
comment said: the rows that did pass are still in stdout's buffer, and a
watchdog that threw them away would tell you less than the hang did.
Also observed firing from test_dev, which is blocked on a daemon rather
than spinning — the case the reader hang does not cover.
