Shadowing special variables in threaded handlers

Attached is the patch I went with courtesy you and Chun Tian - it works
very nicely, thank you both :)

In summary, the approach I took was:

 1. Use a helper to create a handler closure that closes over the
 shadowed variables, thereby making the correct values available on all
 threads.

 2. Add the root path to the request class, conceptually treating
 requests as relative to a particular root, and handily avoiding the
 same threading + shadowed variable issue with *germinal-root*.

Now I can set a temporary context in my tests with a let form, and the
world is a happier place :)

Happy New Year :)
