Just another quicksort implementation, to see if I memorized the algorithmn.
Apparently, yes. :-)

Gotchas during the implementation:
- forgot to check min and max in the beginning, got IndexError
- choosing nonsense as pivot led me to almost-sorted list (worked when
I stopped being stupid)

This is an attempt of an alternative to
http://code.activestate.com/recipes/577068-floating-point-range/
but generating the expected floating-point elements in the range,
avoiding floating-point arithmetic problems.

Currently it works rather well, although without the original
validation steps (which seem to be overengineering to me), considering

# This was a little experiment I've put together in some minutes while in TDC2011 (The Developers Conference), at São Paulo
# It's just a silly almost-Hello-World, just to show the assynchronous communication working with non-blocking I/O through event loops, mixed with a simple HTTP server

# First, put this on a file called 'server.py', and run:
