Not the easiest to track down to why its crashing. Also based on other 
patches in flight it looks like their are questions about that changes.

For me should I not based my patches on lustre-testing and test it their 
so it is stable. Would you do testing of the lustre branch in that case
or do I need to make sure my patches apply to your tree? Note some patches
I have will collide with what you are doing.
