If you want to use a toolkit, XView supplies a function called 
notify_do_dispatch which will process window events while waiting for
input on a file descriptor (like a user typing 'S' to stdin).

I already posted code about this subject to this list, so I will not clutter 
it again with a repeat.  See the on line XView examples for an example.

If you don't want to use the XView UI, it is still possible to use the
XView notifier as an input distribution mechanism.

Caveat: notify_do_dispatch requires that your OS has syscall() since it
	replaces the default select() and read() system calls with its own
	version.
