Hi Sam,

I stumbled upon what seems to be a leak at http://pulpito.ceph.com/loic-2=
015-01-29_15:41:06-rados-dumpling-backports---basic-multi/730305/ and the=
 valgrind xml file is at http://tracker.ceph.com/attachments/download/161=
0/v.txt=20

A quick grep of get_object_context in redmine does not hit. Does it ring =
