How do you debug memory usage?

Thanks for the logic.

I want to debug rdiff-backup (Python backup tool for Linux) - it's
using 2 GB of memory (1GB ram, 1GB swap) on a backup server at work.

I'll use your method to find out why this is happening. Even if it
doesn't give me exact details, it should be enough info to go by.
