Writing a resume handler would just patch over the problem, because this
problem can also show up without suspend&resume (typically, you're
behind a NAT router, and you leave the connection idle for a while,
after which the NAT router decides to forget about this connection).
Presumably setting the `keepalive' bit on the TCP connection should help, but:
- we should also make sure that C-g works.
- we should time out (hopefully keepalive does it for us) after a while.
- we should figure out what other applications (e.g. other MUAs) do.
- we should make it easy for the user to kill the connection if it is
hung (e.g. make C-g kill the connection).
