That's a nice to have needing more effort...

...but right now there will be a benefit to having comp make its single
attempt with O_EXCL;  explicit abandonment with an error message showing
the problem rather than silent trampling and a random winner.  And it's
a simpler change.

Doing O_EXCL doesn't preclude other strategies being on a wish list.
