Hi Thomas, Greg et al,
I am at LPC and will present a talk on Wednesday 5:15pm at the kernel summit about object life-time issues. I'll reference this problem among others. Please consider it in your schedules, I think it'll be useful to discuss it in person as it's a generic problem in many driver subsystems.
