EBADF would be returned, except if another thread creates a fresh listen socket between the 'close' and the 'accept' (which may happen to get the same number as the socket that was just closed). Hence it is a race (with MHD, we should not make assumptions about what the rest of the program might be doing...). Happy hacking, Christian
