Interesting, I've been using it to test install s/w and found it completely 
stable. Not once have I seen it crash using snapshot.

Indeed I've built on Linux and moved the client O/S's to both Windows and MAC 
and vice versa. The volume is not all that high, maybe 20 restores of a single 
snapshot, over and over. 

I wonder what the conditions were that it failed under?
