Here's something I wanted to park here to look into for the next
cycle: it turns out that kqueue's EV_EOF flag also has the right
semantics for this. That leads to the idea of exposing the event via
the WaitEventSet API, and would the bring
client_connection_check_interval feature to 6/10 of our OSes, up from
2/10. Maybe Windows' FD_CLOSE event could get us up to 7/10, not
sure.
