[sldev] Cache speed experiment & results...

[Alex Dailey]

A humorous side note to this. The distribution of uuid's is so random 
and there is so much 'space' between values, that Cory et al. joked 
about putting phony assets in the early range, ...0000000, 0000001 that 
rezz'ed signs saying things like, "Give up now!" and "Abandon your quest 
or despair!" for people who tried to guess asset_id's starting from the 
beginning of the uuid range.
