I can see at least one problem - which needs to be addressed somehow.

Operations like lvremove are currently locking whole executable
to RAM - which is reasonable small (20MB) in case it's just native lvm binary,
but it may get unusable huge when Python steps in the game.

If the lvm2api is going to be used this way - we will need to add
some option  which would disable memlocking for this code - and user would
need to enable it probably explicitly.
