I've not had any trouble using that option but then I tend not to have
too many files open once I've mounted the drive. IIRC the main
warnings about using the option was that memory isn't freed until the
drive is unmounted and as a result would gradually eat up your RAM the
more files you had open etc etc. I could be wrong though ;-)

You'd end up with da0s1 and da0s2 (for example).
