I am irredeemably slack for not testing this a lot but...

I believe I saw bad interactions between vmiodirenable and isofs on 4.3-R.

I mounted a CD, looked at stuff on it, did a lot of other work, went back
to the CD and files were screwy (files contained the contents of other
files, files were zero size).  I unmounted and remounted the CD and
everything was fine.  The machine is a reliable old workhorse, and has
no hardware errors.

Since then, I've not had a chance to go back and check.  It's only because
you are making vmiodirenable the default that I'm mentioning it.  Sorry
for not making a proper bug report containing actual facts. :-(

Stephen.
