what is the purpose of scala.tools.util.SocketServer?

A:
It's part of the compiler, and not a part of the standard scala library.
Its purpose is to implement the server communication for the fsc (fast scala compiler). When you're compiling with fsc a server daemon process is started. This is done by starting up the scala.tools.nsc.StandardCompilerServer, which is a subclass of scala.tools.util.SocketServer. Once the fsc server is running, you avoid the overhead of having to start up a new JVM instance with every compilation that you do, which happens when you use scalac instead of fsc to compile your code.
