   3 /* A server puts itself on an idle queue for a service using an
   4  * instance of the following structure.  When a call arrives, the call
   5  * structure pointer is placed in "newcall", the routine to execute to
   6  * service the request is placed in executeRequestProc, and the
   7  * process is woken up.  The queue entry's address is used for the
   8  * sleep/wakeup. If socketp is non-null, then this thread is willing
   9  * to become a listener thread. A thread sets *socketp to -1 before
  10  * sleeping. If *socketp is not -1 when the thread awakes, it is now
  11  * the listener thread for *socketp. When socketp is non-null, tno
  12  * contains the server's threadID, which is used to make decisions
  13  * in GetCall.
