Demonstration of sharing file descriptors across processes
#!/usr/bin/env python
"""This is a demonstration of sharing file descriptors across processes.
It uses Tornado (need a recent post-2.0 version from github) and the
multiprocessing module (from python 2.6+). To run it, start one copy
of fdserver.py and one or more copies of testserver.py (in different
terminals, or backgrounded, etc). Fetch http://localhost:8000 and
you'll see the requests getting answered by different processes (it's
normal for several requests to go to the same process under light
load, but under heavier load it tends to even out).

print out ascii tables in python using data in the form: [ ('column 0 title', 'column 1 title' ..), ('row 0, column 0 data', 'row 0, column 1 data' ...) ...]
# I needed to print out ascii tables from data in the form:
# [ ('column 0 title', 'column 1 title' ..),
# ('row 0, column 0 data', 'row 0, column 1 data' ...) ...]
#
# and surprisingly it got complicated because of variable lengths of the data.
# I googled for 'standard' ways of doing this and I found suggestions like:
# http://stackoverflow.com/questions/5909873/python-pretty-printing-ascii-tables
# ...which were a bit dated and hard to read or full scale modules like:
