+Hook to invoke when there's nothing left on the runnable threads
+queue {\em and} we've got nothing to wait for. The value
+returned is the exit code to report back.
+
+NOTE: This hook is really CONCURRENT specific, but we include
+it in the way-independent libHSclib.a.
\begin{code}
-#ifdef CONCURRENT /* the whole thing! */
#include "rtsdefs.h"
-void
+int
NoRunnableThreadsHook (void)
{
+ fflush(stdout);
fprintf(stderr, "No runnable threads!\n");
+ return(EXIT_FAILURE);
}
-#endif /* CONCURRENT */

\end{code}
