/* The matrix which drives the serialization algorithm. The major index */
/* (the first) into this table is the command being checked and the minor */
/* index is the command against which the first command is being checked. */
/* i.e., the major index (row) command is ahead of the minor index command */
/* (column) in the queue. This allows the code to optimize by capturing */
/* the result of the first indexing operation into a pointer. */

/* Whenever a new value is added to the IDX_T type, this matrix must be */
/* expanded by one row AND one column -- Because of this, some effort */
/* should be made to re-use the indexes whenever possible. */
