Why should we care what you "doubt" and "suspect" when it's all guesswork?
If you attended any of the SVR4 presentations, such as the AT&T BOF at the
Baltimore Usenix, it would have been quite apparent that the SVR4
implementation has little in common with BSD, other than a common 7th
Edition UNIX heritage.  Its memory management, like SunOS's, is entirely
different.  Its character I/O system is entirely different.  Its general
filesystem support is entirely different (although one module does support
BSD filesystems as a special case).  Its network base is entirely
different, although some of the "r-commands" may have been adapted from
BSD versions.  And in general it makes the current BSD release look sick.
