+  Example socket server
+
+  Code from original drsdaq socket thread
+  
+  This code will block execution in the accept() and read() socket function
+  while waiting for a connection or data. To terminate, these blocking functions
+  must be interrupted by raising a signal (e.g. SIGUSR1). Testing on errno=EINTR
+  then indicates this.
