After starting slattach from sh, csh or ksh on a RC3230 or an M/120 running
4.50, one sees the following (mis)behaviour:

- "tty" run on the shell reports the tty on which the login took place, as it
  should.
- ps, however, reports that no terminal is associated with the shell or any
  process started under it.
- attempts to fire up programs that expect a controlling terminal (e.g. "su")
  will fail ("su" will actually give a Memory Fault, what fun, when it can't
  open /dev/tty -- ought to check return values of open, neh?)

Note that slattach is not being performed on the port where the login took
place, and that it does not matter whether the slattach-ed port is a Mips
CPU port or a tty port on our local communication board.

Fixed in 4.50B, Roger :-)?

p.s. anyone done Van Jacobsen compressed header slip under 4.50 before I go
ahead and do it?
