Here's a patch that I think implements this ;) Alvaro - do you have a build
env so you can test it? I can't reproduce the problem in my environment...

Also, it currently just silently loops. Would it be interesting to
ereport(WARNING) that it's looping on the open, to let the user know
there's a problem? (Naturally, only warning the first time it tries it on
each file, so we don't spam the log too hard)
