easy in C (well, it takes 18 lines...), but there's nothing in the standard Haskell libraries that can do it. So I borrowed a little C code from the net, and called it via the FFI.
Locking support is available in the unix package distributed with GHC. See:

That'll teach me not just to look in the standard Haskell 98 libraries! Thanks. john
