I think there will be a race condition around the time of a database
shutdown. After a new child process is created, the system may go into
shutdown mode. However, there is a window where the child won't know
this, because the signal is blocked and/or not set up yet. Note that we
cannot check for shutdown before forking the child because we won't know
yet whether the incoming packet is actually a connection request. We
wouldn't want to send back an error in response to a cancel request, for
example.
Any ideas?
