IMHO we should just implement the \setrandom changes, and not add any of 
these options to modify the standard test workload. If someone wants to 
run TPC-B workload with gaussian or exponential distribution, they can 
implement it as a custom script. The docs include the script for the 
standard TPC-B workload; just copy-paster that and modify the \setrandom 
lines.
