I like this option the most because it is the most "fail fast". If you

DiskIO appears to not be interruptable. For example:

Pressing Ctrl-C (on Linux with python 2.6.4) will not interrupt the

I have many times screwed up "while True"-loops. When I thought I had
a safe exit condition which turned out to be never reached in some

reformulate "while True"

Hello everybody,
I'm looking for a pure Python solution for converting word documents
to text. App Engine doesn't allow external programs, which means that

Linux distros will acquire a symlink at /usr/bin/python2 pointing to

This is maybe not so efficient :) but it implements integer division
by 7 for positive integers without - and /.
