In 1.9, you don't need to.  Block parameters shadow local variables,
such that this works fine:

 Thread.new(request) { |request| ... }

In 1.9, 'request' inside and outside the block are different variables.

(I'm still not entirely sure I'd recommend calling them the same thing,
for readability's sake, but you can do it now...)
