-/** Generate a random amount of symbols and destroy them again immediatly.
- *  This operation effectively makes the serial numbers of all subsequent
- *  symbols unpredictable.  If the serials are unpredictable, then so are
- *  their hash values.  If the hash values are unpredictable, then so are
- *  the canonical orderings.  If the canonical orderings are unpredictable,
- *  all subsequent times are subject to some variation.  This variation,
- *  however is natural and desireable for two reasons: First, we cannot know
- *  how many symbols have been generated before in real world computations.
- *  Second, the following timings are subject to some semi-random variation
- *  anyways because short timings need to be repeated until enough time has
- *  gone by for the measurement to be reliable.  During this process the serial
- *  numbers will be shifted anyways in a semi-random way.  It is better not
- *  to lull the user in a false sense of reproducibility and instead confront
- *  her with the normal variation to be expected.
