	Seth advocated a "better safe than sorry" policy on this issue
for quite some time, restricting us to 50 million bytes.  We did get
an actual number from our production folks saying that it was actually
closer to 53MB decimal for the media we use.  

	I think that it's a sargasso sea of number systems, orders of
magnitude, and media conversion formulae.  So far we've tried to keep
to 50 binary megabytes (50 * 2^20, or 5242880 bytes), because it's a
reasonable outcome of the label "50MB", because it fits under the 53M
bytes our vendor told us, and because it has a 242 sighting in the
decimal form.
