I get bitten by this quite a lot, since I'm often on a flaky 3g
line. When the link goes down, and some Emacs socket is still up, Emacs
freezes. This is quite annoying.

I suppose that the hard blocking is there to prevent data loss or
whatever, but having to kill -9 Emacs results in worse dataloss.
