     There is some strangeness going on here. It looks like algorithms
     at the end take some kind of penalty. For example, running the RW tests
     first got a result of:
         RW-1024: 148.14 ms / private operation
     but running them last output:
         RW-1024: 363.54 ms / private operation

     I think it's from memory fragmentation in the allocators, but I'm
     not really sure. Need to investigate.

     Until then, I've basically ordered the tests in order of most important
     algorithms (RSA, DSA) to least important (NR, RW).

     This strange behaviour does not seem to occur with DH (?)

     To get more accurate runs, use --bench-algo (RSA|DSA|DH|ELG|NR); in this
     case the distortion is less than 5%, which is good enough.

     We do random keys with the DL schemes, since it's so easy and fast to
     generate keys for them. For RSA and RW, we load the keys from a file.  The
     RSA keys are stored in a PKCS #8 structure, while RW is stored in a more
     ad-hoc format (the RW algorithm has no assigned OID that I know of, so
     there is no way to encode a RW key into a PKCS #8 structure).
