    vos: convertROtoRW susceptible to VLDB changes during override prompt
    vos convertROtoRW obtains a VLDB entry, then peforms some setup logic
    (including a possible user prompt) before obtaining a volume lock.
    This exposes the code to possible time-of-check/time-of-use issues.
    After obtaining the volume lock, get a second copy of the VLDB entry
    and compare it to the first copy; if it has changed, fail the conversion
    with an error message asking the user to re-issue the vos convertROtoRW
