-------------------------------------------

bq.  but doing so mean that we will need to guarantee to 2 updates with the 
same (user provided) timestamp actually do conflict

:(

bq.  It's not like we can't change this if we really need to later.

Good point. Ok then I'll update to use the classpath and PID only.

> TimeUUID LSB should be unique per process, not just per machine

>  lsb collisions are also possible serverside.
> a sufficient solution would be to include references to pid and classloader
