Simple test checking that EGL can close the export file handle
and the creator can in turn can its reference.
Without a verb, the second phrase above is a bit too elliptical. How about
"can in turn $VERB its reference"?

I don't see how this test verifies the above spec quote. I think you need,
as Eric suggested previously, to call close(fd) after eglDestroyImageKHR
and check that it returns EBADF.
