 Every method to preserve ADA-likeness has been used,
 at the expense of C-ness.

Version History:
 Version 1.1 corrects two bugs in version 1.0:
 First, it leaked memory: in Proc1(), NextRecord ends
 up having a pointer to itself. I have corrected this
 by zapping NextRecord.PtrComp at the end of Proc1().
 Second, Proc3() used the operator != to compare a
 record to None. This is rather inefficient and not
 true to the intention of the original benchmark (where
 a pointer comparison to None is intended; the !=
 operator attempts to find a method __cmp__ to do value
 comparison of the record). Version 1.1 runs 5-10
 percent faster than version 1.0, so benchmark figures
 of different versions can't be compared directly.
