+   Define INTERRUPT_INPUT to make interrupt_input = 1 the default (use SIGIO)
+
+   SIGIO can be used only on systems that implement it (4.2 and 4.3).
+   CBREAK mode has two disadvatages
+     1) At least in 4.2, it is impossible to handle the Meta key properly.
+        I hear that in system V this problem does not exist.
+     2) Control-G causes output to be discarded.
+        I do not know whether this can be fixed in system V.
+
+   Another method of doing input is planned but not implemented.
+   It would have Emacs fork off a separate process
+   to read the input and send it to the true Emacs process
