- now there's no SAMI_recv(), but handler is called each time message
  is received
- children can send messages to their parent, which is obtainable
  using SAMI_parent()

 DESCRIPTION
      sami is a library for handling actors.  It uses fork(2) for making
      actors, and unix(7) sockets for message delivering.
 
 RETURN VALUE
-     All functions return 0 on success, and any other number on failure.
+     Functions usually return 0 on success, and any other number on failure.
      Consider checking errno(7) in the latter case.
 
+     SAMI_parent() returns a valid pointer.
