The file lib/digest.scm, which computes digests (CRC32, MD5, SHA-1,
etc), has been optimized. The new version is on the repository.
Essentially it now does all computations with fixnums (the old version
did many operations on bignums and the fixnum operations were not
inlined). Digest computation of a 1MB file is over 100 times faster
than the previous version!
