Hello,

(Not having received a single answer, I repost this...)

I tried to use "bedup" BTRFS offline deduplication tool on several BTRFS 
machines, with mixed results :

1/ Crashes with messages stating "programming error", sqlite objects must be 
used inside of the thread that created them, blah-blah...

2/ Crashes stating that some file/objects miss a "live" attribute (?)

3/ bedup eating all my system RAM, then swap over 7GB until the system trashes 
itself.

Wel, besides that and restarting over and over, I could deduplicate some files 
and gain some noticeable space, but it looks extremely bugged and unreliable.

I tried to email the maintainer with details, twice, thru 2 different channels, 
got no anwser...

And it looks like the GIT has not evolved since August, 2013.

So my questions are : 

- Is "bedup" maintained or abandoned ?
- Is it supposed to be usable ?
- Should I use it ?
- Is there a risk that it causes data loss or corruption ?

TIA.

Kind regards.
