While working on lvm2 testsuite problem with similar symptoms,
Mikulas Patocka found a race condition that caused kernel to occasionally
return "/" instead of a full path in the file /proc/self/maps
(the same bug affects other paths returned in the /proc filesystem
or elsewhere by the kernel).
Problem he observed with lvm2 started with commit:
232d2d60aa5469bb097f55728f65146bd49c1d25
and should go away with combination of:
