Adventures in Python Core Dumping

After watching Bryan Cantrill's presentation on [Running Aground: Debugging Docker in Production][aground] I got all excited (and strangely nostalgic) about the possibility of core-dumping server-side Python apps whenever they go awry. This would theoretically allow me to fully inspect the state of the program at the point it exploded, rather than relying solely on the information of a stack trace.

Go to Steam Licenses List and login your account.
Use browser javascript console (such as F12 on Chrome/Firefox)
Execute javascript code, after console display Object {readyState: 1}
```
 jQuery.ajax(
 {
         type:'POST',
```

dataType:'text',

	Just paste into your console.. or make a tampermonkey/greasemonkey script out of it.
	Only tested in Chrome. Be careful.. three tabs are opened per book.

	If a books image is not removed, you'll need to try to download that book yourself.

	Use this script (enter into the console of your browser) on the following pages:
