That strikes me as a problem.  As a naïve user, I would expect
specifying oflag= without O_CREAT would make the open() call not pass
O_CREAT.  I certainly think that the lack of a way to turn off O_CREAT
is a problem with anything that is designed to give control over the
flags passed to open().

It is?  Why is it not O_WRONLY?

This makes three "no way to clear it"s.  Perhaps that should be
changed?
