Daniel is right about the eval server, but it may not be fast enough
The file "ccl:library;mactcp.lisp" provides a TCP stream. It does NOT
provide good support for one of the sides of the connection being a server.
To do this right, you really need multiple threads, which MCL doesn't
have (yet). I'm sure you can do it with polling in the existing MCL,
but that solution will not work very well if any of the requested
services takes a long time. I remember someone saying that "mactcp.lisp"
doesn't support passive opens very well, but I don't know the details.
