Code Feedback

[mwt]

Hello -
Last night I wrote my first code in Python -- a little
producer/consumer toy to help me begin to understand things. The
"Library" only has a few books. You can choose how many Readers are
trying to check out the books. When no books are available, they have
to wait until some other Reader returns one. Readers are assigned
random reading speeds and wait times between

It runs fine, but I have a few questions about it.
1) Is this good Python code? What should be changed to make it more
Pythonesque?
2) Anybody know how to alter the "while 1: pass" section to make the
app stoppable?
3) The synchronization I'm using works, but is there a better way to do
it?

Thanks for any insight/pointers, etc.

Also, for any newbies like me, feel free to post variations of this
code. In the next version, I'm going to make it so that readers can't
check out the same book twice.

Here's the code:
