CLISP has to open with O_RDWR to use buffering, so :DIRECTION :OUTPUT
means O_RDWR too.  This breaks write-only files, like Peter's /proc
file.

I guess we should document "the obvious" - that one cannot use
buffering on write-only files - and use O_WRONLY with :BUFFERED NIL
:DIRECTION :OUTPUT.

yuk!
