Issue 'openssl speed' and wait for more numbers.

Short lived hybrid sessions kill (not that this or any of the current 
reasons for asynchronous crypto really matters imho).

Instant benchmark:
                  sign    verify    sign/s verify/s
rsa 1024 bits   0.0148s   0.0008s     67.7   1198.6 (PIV 2GHz)
                  sign    verify    sign/s verify/s
rsa 1024 bits   0.0478s   0.0026s     20.9    381.6 (PII 350MHz)

The 'numbers' are in 1000s of bytes per second processed.

blowfish is ~10x faster btw.
