*                   EQUIPMENT LOCK TABLE
* 
*  THE EQUIPMENT LOCKING TABLE IS USED TO LOCK AN EQUIPMENT 
*  TO A PROGRAM AND TO HANG A LINKED LIST OF REQUESTS WAITING 
*  EITHER FOR USE OF THAT EQUIPMENT, OR TO LOCK THAT EQUIPMENT
*  TO THEMSELVES. 
*  ENTRY POINT $ELTB CONTAINS A POINTER TO THE TABLE (TO THE TABLE
*  HEADER, IN FACT).
*  THE TABLE HEADER, NAMED "HEADR" BELOW, IS ONE WORD LONG, AND 
*  CONTAINS THE TABLE LENGTH (# OF 3-WORD ENTRIES IN TABLE) IN ITS
*  LOWER BITS, AND THE UPPERMOST BIT IS SET IF THE TABLE HAS CUR- 
*  RENTLY AT LEAST ONE NONBLANK ENTRY (I. E., IT IS THE TABLE_
*  NOT_EMPTY BIT).
*  THERE FOLLOWS THE FIRST WORDS OF ALL ENTRIES, FOLLOWED BY THE
*  SECOND WORDS, AND THEN THE THIRD WORDS.
*  THE FIRST WORD OF EACH ENTRY, WHEN NON-ZERO, IS AN EQUIPMENT #,
*  LOCKED TO THE PROGRAM WHOSE ID SEGMENT ADDRESS IS IN WORD 2 OF 
*  THAT ENTRY.  BIT 15 OF THIS WORD 2 IS SET IF THE EQT. LOCKING
*  REQUEST SPECIFIED THAT THE EQUIPMENT SHOULD NOT BE RELEASED IF 
*  THE PROGRAM TERMINATED PREMATURELY (I. E., IT IS THE LOCK_ON_
*  ABORT BIT).
*  WORD 3 OF EACH ENTRY, WHEN NON-ZERO, POINTS TO A LINKED LIST 
*  OF $XSIO REQUESTS (FROM THE OPERATING SYSTEM) FOR THAT EQUIP-
*  MENT ISSUED SINCE THE LATTER WAS LOCKED, TO BE REHUNG ON THE 
*  EQT FOR THAT EQUIPMENT WHEN THE EQUIPMENT FINALLY IS UNLOCKED.
