-- Module : Foreign.Concurrent
-- ^Turns a plain memory reference into a foreign object by associating
-- a finalizer - given by the monadic operation - with the reference.
-- The finalizer will be executed after the last reference to the
--- foreign object is dropped. Note that there is no guarantee on how
--- soon the finalizer is executed after the last reference was dropped;
--- this depends on the details of the Haskell storage manager. The only
--- guarantee is that the finalizer runs before the program terminates.
+-- foreign object is dropped. There is no guarantee of promptness, and
+-- in fact there is no guarantee that the finalizer will eventually
+-- run at all.
