I should have posted this earlier, but the exact message I'm seeing in the case where the Bad Client disconnects is this:hums: Network.Socket.SendFile.Linux: resource vanished (Broken pipe)Oddly, I haven't been able to reproduce this using a wget client with a ^C during transfer. When I "disconnect" wget with ^C or "pkill wget" or even "pkill -9 wget", I get this message:hums: Network.Socket.SendFile.Linux: resource vanished (Connection reset by peer)(and no leak, as observed by "lsof | grep hums").
"Broken pipe" is normally handled as a signal, and is only mapped to an error if SIGPIPE is set to SIG_IGN. I can well imagine that the SIGPIPE signal handler isn't closing resources properly; a workaround would be to use the System.Posix.Signals API to ignore SIGPIPE, but I don't know if that would work as a general solution (it would depend on what other uses of pipes/sockets exist).
