If this was multiple clients I could see that possibility, but the

graph in which this isn't true?

There are some subtle races which were discovered in the context of using elasticsearch with a single gluster client [1]. Some races have been addressed and some are still open yet. The referenced bug has a lot of details, the upstream clone [2] has the list of patches evolved to address these races. Please go through these bugs and let us know if you need help in understanding more.

Thanks,
Vijay
