  CMU-CL is NOT ready to be used. It does NOT have a working
debugger/single stepper. It does NOT have threads. (You need threads
if you are going to write deamons!) Since I haven't seen anyone
volunteer to help the CMUCL on 386 guys implement the things we need,
we're at their mercy as to if and when that functionality is

  Kelly is planning on implementing a proof of concept/demo of the
idea of building a system based upon POS ideas instead of file
systems. He want to use the SMTP agent as an example. He's NOT
claiming that what he's doing is the final, full featured SMTP agent.
