Well, if a hashtable is used for the duplicates, and any fast
half-believably-random number generator is used, then this solution is
sufficiently fast, even for an underclocked 80286.

The real reason that random numbers may be less appropriate is that it
makes a .pd (or .pd-xml) patch look more noisy. Which is not sooo much of
an issue either, but still more so than "performance".
