Definitely not a nice situation. But from my (oh $god knows) limited
understanding of the great picture, when does that happen? File server
shutdowns? Wouldn't it be much nicer to make a "don't accept new
connections, wait X seconds for the clients to clunk, if time is over,
just clunk"-function. No other situations, none that I could think of,
would result in the situation you described.

I don't know limbo well, but I don't know how it could work without
close() in any way. Else see my rave above.
