Unsurprisingly, I don't see any such problem under Unix (HPUX to be
specific, but I'd be astonished to see PG on any Unix do that,
considering that each backend manages its open files independently).

I think you must be looking at some misbehavior of the Cygwin layer.
If the problem really did go away in 7.1.3, perhaps some fix was applied
by the Cygwin packager and not contributed back to the main code base.
But it's got to be a Cygwin bug anyway; the most we could do is find
some workaround to avoid triggering it.
