Pruning Duplicates

[Wesley Craig]

I've seen this before with Thunderbird.  As I recall, Thunderbird  
requests a lengthy operation but times out (or fills a buffer?)  
before getting a result back.  It then tries the operation again,  
until the mailbox is woefully full.

To clean up, we typically calculate checksums on the files and find  
duplicates that way.
