Re: [Haskell-cafe] createProcess interferes with sockets?

Quoth Evan Laforge ,

sleep = Process.createProcess (Process.proc "sleep" ["5"])

sleep = Process.createProcess ((Process.proc "sleep" ["5"]) {Process.close_fds = True}) - Because the client uses buffered I/O (hGetContents in this case, but hGet-anything would be the same), it doesn't "see" the server response until a) buffer full, or b) end of file (server closes connection.) - The server does close the connection, but after the "sleep" process has forked off with a copy of the connection fd. If it doesn't close that fd explicitly, it holds it open until process exit (5 seconds.) Donn
