I don't understand. read() is a blocking method, so if there
is no input it blocks until there is input. It returns -1
if end of stream is reached (and stream is then invalid and
no point in calling read again).

You can easily write am InputStream class that pause a bit before
returning from read(), but does that really make sense?
