It might not be the best solution long term, but I could achieve 
substantial improvement without a great deal of effort.  See

   http://tug.org/pipermail/tlbuild/2014q4/003072.html

isn't aware of the issues involving the order of the postinstall 
scripts, but I could do everything he suggests if I had a perpetual 
"after" postinstall script.
