@ -22,6 +22,27 @@ fractions once bignums are working.
So we're down to eight unit tests failing: the memory leak, one unimplemented
feature, and the bignum problem.
At the end of the day I decided to chew up some memory by doing a series of
moderately large computations, to see how much memory is being successfully
deallocated.
```lisp
:: (mapcar fact '(1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20))
(1 2 6 24 120 720 5,040 40,320 362,880 3,628,800 39,916,800 479,001,600
1,932,053,504 1,278,945,280 2,004,310,016 2,004,189,184 4,006,445,056
3,396,534,272 109,641,728 2,192,834,560)
::
Allocation summary: allocated 10136; deallocated 548; not deallocated 9588.
```
So, about 5%. This is still a major problem, and is making me doubt my reference
counting strategy. Must do better!
Note that the reason that the numbers become eratic past about two billion is
the bignum arithmetic bug.
