I am in favor of using virtual 8086 modes for the performance gain it would
have over a fully emulated version.  If the Linux DOS emulator uses a 386 
dependent implementation we might be able to borow from its design.  I don't
know much about linux but I get the feeling it has a different approach for
memory management and CPU scheduling.  This would make a direct port
difficult.  Nevertheless, it could be worth taking a look at as a starting
point.  Any Linux users out there care to comment about this?

If enough people are interested in being on a mailing list, we could add a
workgroup to ref.tfs.com.  Anyone who would like to be on it can send me
email or post to this thread.  I'll ask Julian to add it to ref if there is
enough interest.
