Built-in support for parallel processing - like fork()'ed sub-processes for multi-CPU and multi-core support and perhaps also for GPU support? I think that for fast hashes this must be done at a higher level in the code. Doing inter-process communication per crypt_all() call would be too slow for those, although for slow hashes this is an option (and it has its advantages).
