Aside, for those who aren't aware, there is tempfile.rb in the Ruby 
standard library which does something similar: i.e. create a random name 
from a template, then open the file.

The names it generates aren't really random, but AFAICT are guaranteed 
to be unique. The documentation for mkstemp doesn't make any claims to 
randomness either though.
