- * Given MIN_SUBR_SEPARATION bytes of separation the value of

- *
- * HASHFRACTION = MIN_SUBR_SEPARATION / (2 * sizeof(short) - 1);
- *
- * For the VAX, the shortest two call sequence is:

- *
- * which is separated by only three bytes, thus HASHFRACTION is
- * calculated as:

- * HASHFRACTION = 3 / (2 * 2 - 1) = 1

- * Note that the division above rounds down, thus if MIN_SUBR_FRACTION
