- Personally, I would most like to find the source of the lost
- character problem that exists even with the "pty" driver that must
- be used to run "mgr".
- Comments follow on some of the other suggestions.

- Might be nice, but is a major nasty project because drivers need to be
- gone through with a fine tooth comb to find references to "volatile"
- registers and such.

- These and other shared library fixes such as the timezone fix
- mentioned elsewhere can be done now. There is documentation and
- an example of how to rebuild the shared library on the archive as
- "library/shlib.sh.Z". Source code is *not* required.

- Yes, and this is practically an insurmountable obstacle because the
- changes to add the code to provide a File System Switch (SVR[34]) or
- VFS (SunOS) are very involved *and* decrease efficiency because of the
- required indirection.
