Note that if you use the minimum unambigous rule, nearly no shell scripts
  would have to be changed. Perhaps a environment variable that controls
  which getopt() syntax table to use.

I didn't call for the removal of I/O from the kernel. I just said that it
  (the I/O kernel subsystem) should be decoupled enough from the rest of
  the kernel to make I/O hardware less-capable of crashing the system.  If a
  non-kernel implementation of TCP/IP can be found that satisfies all the
  performance and semantic requirements, I'm all for it.  I've been involved
  in playing with the KA9Q code, and concluded that the only way to get
  it "nice" is to put it in the kernel as a pseudo-device driver.

No.  History buffers of a user-selectable arbitrary size don't belong in
  the kernel, which I why I suggested the callback-like interrupt mechanism.
  Other mechanisms, as I said, might suggest themselves.
