LVM2 can't be embedded in an application because there are points where
if LVM crashes, the whole system must be rebooted.  Furthermore, there
are points where accessing memory that is not mlock'd might hang
forever.

If you plan to frequently perform LVM operations, then LVM is probably
the wrong tool for the job.  LVM operations often take 0.3 seconds or
more and are highly disruptive to other I/O on the system.
