Getting Process Info from iOS 5's LowMemory Diagnostic Reports

In iOS 5 (the latest version of Apple's OS for iPhones, iPads, etc), you can look at the diagnostic reports that it sends (if you have okayed this) to Apple via the "Settings" app.
The diagnostic reports are in the section:
General >> About >> Diagnostics & Usage >> Diagnostics & Usage Data

I wrote a Python script that extracts info from the LowMemory reports. It prints out the names of the processes and the amount (in MB) of memory that each was using.
Here's the script: processLowMemReport.py
(It is published under the MIT licence.)

Sample output (from my iPhone 3GS):
