 ## Concurrency
 
 
+
+The concurrency support in Haskell' will be based on the Control.Concurrent library, with minor modifications. There will be a thread-safe interface for mutable state,
+suitable for use in library code that does not otherwise use concurrency (though what it will be based on is an open issue). There will also be independent FFI annotations
+for specifying whether foreign calls are concurrent (with other Haskell threads) and reentrant. Bound threads will not be required by the concurrency standard, but they
+will be an allowed extension with a specified meaning. Open issues include whether standard will require preemptive concurrency, the syntax of the new FFI annotations and
+the memory-model semantics of IORefs.
