Given a directory with statedumps captured at different times if
there are any stacks that appear in multiple statedumps, it prints
them.
Sample output:
glusterdump.25425.dump repeats=5 stack=0x7f53642cb968 pid=0 unique=0 lk-owner=
glusterdump.25427.dump repeats=5 stack=0x7f85002cb968 pid=0 unique=0 lk-owner=
glusterdump.25428.dump repeats=5 stack=0x7f962c2cb968 pid=0 unique=0 lk-owner=
glusterdump.25428.dump repeats=2 stack=0x7f962c329f18 pid=60830 unique=0 lk-owner=88f50620967f0000
glusterdump.25429.dump repeats=5 stack=0x7f20782cb968 pid=0 unique=0 lk-owner=
glusterdump.25472.dump repeats=5 stack=0x7f27ac2cb968 pid=0 unique=0 lk-owner=
glusterdump.25473.dump repeats=5 stack=0x7f4fbc2cb9d8 pid=0 unique=0 lk-owner=
NOTE: stacks with lk-owner=""/lk-owner=0000000000000000/unique=0 may not be hung frames and need further inspection
