As a remedy to the problem when a socket gets closed and a new one is opened with the same file descriptor number and as a result multi.c:singlesocket() doesn't detect the difference, the new function Curl_multi_closed() gets told when a socket is closed so that it can be removed from the socket hash. When the old one has been removed, a new socket should be detected fine by the singlesocket() on next invoke. Bug: http://curl.haxx.se/bug/view.cgi?id=1248 Reported-by: Erik Johansson
