This is a problem I have had as well. My problem was with some optical drives
e.g. Panasonic PD drive then mean the disklabel did not get reloaded
when I swapped disk. I just added a bit to sdclose() to clear this
flag on the last close.
I suspect that in my case the drive is meant to report a unit attention
command when the media is changed (this will cause a disklabel re-read)
but the pd drive does not do this which means that is it very easy to
trash PD discs unless sdclose is fixed.
