+
+	* java/lang/PosixProcess.java (exitValue): Implement here. Throw 
+	IllegalThreadStateException if process hasn't exited yet.
+	* java/lang/natPosixProcess.cc (exitValue): Removed.
+	(waitFor): Only check thread interrupted status if waitpid() returned
+	an error. Use WIFEXITED and WEXITSTATUS to process process's exit
+	value.
