Well, I'm not. I'd be perfectly happy to pay my share if someone were to 
offer a solution that actually works. Not quite a million dollars but a 
couple of hundred for sure. After all it's our source repository we are 
talking about.

Thanks I'll try this. I hadn't applied these changes to that particular 
image (mostly because I try to touch a working installation as little as 
possible) but to the best of my understanding of the situation the 
problem always occurs when it tries to save a snapshot of the data. 
Which is really not that surprising if you consider what I wrote a while 
back about saves being locked against each other but not serialized with 
incoming modification requests.
