Comment (by kooda):

 I’ve investigated this bug a little, and it seems to be caused when
 reading or writing to the socket causes a broken pipe exception. The
 sockets seem to stay half-open even after the ports have been closed.

 Forcing the socket closing with `file-close` (in spiffy) makes the issue
 disappear.

 I’ll have to dig a bit more, I don’t know what the POSIX spec says about
 the state of sockets in this case.
