Subject: [Caml-list] Child process doesn't terminate

Hi,

In the following program, the child process "cat" never terminates. I 
don't understand why; can anyone tell me?

~~~
let _ =
   let open Unix in
   let indescr, outdescr = pipe () in
   let outchan = out_channel_of_descr outdescr in
   let pid =
     create_process "/bin/cat" [|"cat"|]
       indescr  stdout  stderr
   in
   Printf.fprintf outchan "Hello!\n%!";
   close indescr;
   close outdescr;
   ignore (waitpid [] pid)  (* stuck here *)
~~~
