I don't have this particular backend anymore, and I don't have lsof. But
in smaps there are libraries listed, so:

Still there is 51MB non-shared block:
2ba63c797000-2ba63fa68000 rw-p 2ba63c797000 00:00 0
Size:             52036 kB
Rss:              51340 kB
Shared_Clean:         0 kB
Shared_Dirty:         0 kB
Private_Clean:        0 kB
Private_Dirty:    51340 kB
Swap:                 0 kB
Pss:              51340 kB

As for libraries:
=> grep / smaps  | awk '{print $NF}' | sort | uniq
