Yes, the Posix library distributed with GHC has support for file locking. See http://www.haskell.org/ghc/docs/latest/html/hslibs/sec-posix.html This library is currently undergoing a rewrite - the functionality will be available under System.Posix in future releases of GHC (and possibly Hugs & NHC). > The second option that I have is to use a daemon and let the > programs that > get started by mail connect via some sort of socket.
