Beats me: System V uses the same file system as V7, with a tweak to allow
512-byte or 1024-byte blocks, so it can handle equally huge files using triple
indirect blocks.  Maybe the people for whom the predecessor of System V was
designed were running PWB/UNIX shops - PWB/UNIX 1.0 had a modified V6 file
system, with no doubly-indirect blocks, which meant they had an absolute file
size limit of 1MB - and they didn't want these people to have to learn
something new, such as how to deal with files larger than 1MB....
