Sorting in memory returns inconsistent queries

[bitliner]

This is a well known issue with Mongo.

It is also described here.

I believe that is not an acceptable issue (because you can't trust the database, because it does not return any warning or error).

I was wondering: how TokuMX manages this issue? Are you aware of it? Does it depend only from the driver to connect to the database?

From the link to the Mongo Issue, it is neither clear which version is affected.

Do you have any more information that could allow me to avoid this issue and help the issue to be more transparent during the usage of an application?
