There are several different versions in situations related to this; I
haven't looked at the source but I think you're correct about what
this one is.
The other big semi-related one is that we increment a version
("retry_version", I think?) every time we send off an operation
because we haven't gotten a response of any kind and the primary OSD
for an op changed or something.
