There is a lot of efforts to improve CPU time, but what about memory usage?

http://shootout.alioth.debian.org/u64q/benchmark.php?test=all&lang=ghc&lang2=ghc

Compared to C versions:
mandelbrot requires 18x memory
k-nucleotide requires 13x memory
reverse-complement requires 4.9x memory


The main problem is with k-nucleotide, that requires a total of 
2,920,980 KB!

For mandelbrot there is an alternate version with better memory and CPU 
usage.
