	But 'volatile' does NOT address *hardware*, it addresses asynchronous
change is a value, which *may* be due to hardware, or to the execution of a
logically asynchronous control thread(either a seperate process or a control
thread in a single process such as a signal handler). It is needed often enough
that I think it makes a meaningful addition to the language.
