I’ve updated patch and wrote description of thighs that happens
with 2PC state data in the beginning of the file. I think now this patch is well documented,
but if somebody points me to places that probably requires more detailed description I’m ready

  "In case of crash replay will move data from xlog to files, if that hasn't happened before."

but I don't see that in code. Can you show me where that happens?
