[linux-lvm] Ignoring locks with the lvm2app API

I find myself in the situation where I want to scan the current LVM2
setup (what volumegroups exist, their logical volumes, etc) without
risking to lock.
That brings me to some questions:
- What's the worst thing that can happen when ignoring locks while
listing logical volumes, reading their properties with the lvm2app
library? Can I do this in a system daemon? A crash of my process
would be OK, as would be getting temprarily inconsistent information.
Permanent damage to the system configuration would not be OK,
- How would I actually best go about ignoring locks? I found some
comments in lvm2app about "better support for locking control", so I
guess it is not really supported right now. I could have a go at
improving this. Would that be worthwhile? Any advice?
