Apple Mail uses the Subject (as text), and I imagine there are other 
applications that do the same.
This of course leads to any number of frustrations, including "re: re: test" 
not being threaded with "re: test", and mail from completely different 
conversations (with the same subject line) being threaded together.

Cheers,
