Compiled by DMD with no optimizations enabled (a common and even recommended way of using DMD), sha.digest.sha.SHA256 and SHA512 can take up to 26x as much time as they would if compiled with `ldc2 -O3`. This can be substantially improved. This problem is not shared by SHA-1 because it uses an optimized SSE3 implementation.
