As a naive user I'd probably expect that each of the above adds to  
the output, which perfectly fits the O_APPEND flag (to be set by the  
shell, of course).

The immediate point was about the flags, though, and having  
O_NONBLOCK on or off certainly is a _design_ choice when writing a  
program. If I remove O_NONBLOCK, I have a right to expect that I/O  
functions do not return EAGAIN!

Ciao,
                     Roland
