- Or hopefully larger, if the poor VAX is expected to be doing anything else at
- the same time! And at least 25% larger to keep from fragmenting the thing to
- death and getting the dreaded "Pagefile space critical" message. DEC actually
- recommends a much larger safety margin than that, for good reason, but be aware
- that you do need at least some margin.
