The build of the entire BBC is usually measured in hours or
half-hours.  Seth David Schoen realized that brute-forcing the first
three bytes of the MD5sum was roughly three minutes.  Since it was
sort of a drop in the bucket, we added his code in.

Basically it just writes random integers on the end of the ISO file,
past the filesystem portion.  It has no effect on the ISO and really
only increases the size by 32 bits.  That, and you can spot
transmission errors pretty quickly.

Also, it makes this page so very pretty:
